+# xPack GNU RISC-V Embedded GCC
+
+This is the **xPack** version of the
+**GNU RISC-V Embedded GCC** toolchain.
+
+For details, see
+[The xPack GNU RISC-V Embedded GCC](https://xpack.github.io/riscv-none-embed-gcc/) pages.
+
+## Easy install
+
+The **xPack RISC-V Embedded GCC** toolchain is also available as a
+binary [xPack](https://www.npmjs.com/package/@xpack-dev-tools/riscv-none-embed-gcc)
+and can be conveniently installed with [xpm](https://www.npmjs.com/package/xpm):
+
+```console
+$ xpm install --global @xpack-dev-tools/riscv-none-embed-gcc@8.3.0-1.2.1
+```
+
+For more details on how to install the toolchain, please see
+[How to install the RISC-V toolchain?](http://xpack.github.io/toolchain/riscv-bone-embed-gcc/install/) page.
+
+## Compliance
+
+Starting with 8.2.0-2, the xPack GNU RISC-V Embedded GCC (formerly
+GNU MCU Eclipse RISC-V GCC) follows
+the official [SiFive releases](https://github.com/sifive/freedom-tools/releases),
+with as little differences as possible.
+
+This release is based on the
+[v2019.08.0](https://github.com/sifive/freedom-tools/releases/tag/v2019.08.0)
+release, and includes the SiFive extensions (like CLIC interrupts).
+
+The following commits (from [sifive/freedom-tools](https://github.com/sifive/freedom-tools/tree/master/src)) were used:
+
+- the [sifive/riscv-binutils-gdb](https://github.com/sifive/riscv-binutils-gdb)
+project, branch `sifive-binutils-2.32`, commit
+[03d23d5](https://github.com/sifive/riscv-binutils-gdb/tree/03d23d58701bdd425c613b0be2d458bcde46912b)
+from 2 September 2019
+- the [sifive/riscv-gcc](https://github.com/sifive/riscv-gcc) project,
+branch `sifive-gcc-8.3.0`, commit
+[e195042](https://github.com/sifive/riscv-gcc/tree/e195042babe2dc30d9fabb88d336d8c8679b3702)
+from from 7 Aug 2019
+- the [sifive/riscv-newlib](https://github.com/sifive/riscv-newlib) project, the `master` branch,
+commit [0d24a86](https://github.com/sifive/riscv-newlib/tree/0d24a86822a5ee73d6a6aa69e2a0118aa1e35204)
+from 9 July 2019
+
+GDB was upstreamed and does not require SiFive specific patches,
+so the current build uses
+`git://sourceware.org/git/binutils-gdb.git`, the `9b40759` commit from
+28 Feb 2019.
+
+## Changes
+
+Compared to the original SiFive version, the **same architecture and API**
+options are supported, and there are minimal functional changes
+
+- `libgloss` was removed from the list of libraires always linked to the
+  application, since it issues `ECALL`
+  instructions that fail in bare metal environments
+- `march=rv32imaf/mabi=ilp32f` was added to the list of multilibs
+
+## newlib-nano
+
+Support for **newlib-nano** is available using the
+`--specs=nano.specs` option. For better results, this option must be
+added to both compile and link time.
+
+## nosys.specs
+
+If no syscalls are needed, `--specs=nosys.specs` can be used at link
+time to provide empty implementations for the POSIX system calls.
+
+## Compile options
+
+The libraries are compiled with `-O2 -mcmodel=medany`. The nano version is
+compiled with `-Os -mcmodel=medany`.
+
+> Important: It is mandatory for the applications to be compiled with
+`-mcmodel=medany`, otherwise the link will fail.
+
+## Documentation
+
+The original PDF documentation is available in the `share/doc` folder.
+
+## Support
+
+For support, please read the
+[support](https://xpack.github.io/riscv-none-embed-gcc/support/) page.
+
+## More info
+
+For more info, please see the xPack project site:

+
+
+Thank you for using open source software,
+

+# xPack GNU RISC-V Embedded GCC
+
+This is the **xPack** version of the
+**GNU RISC-V Embedded GCC** toolchain.
+
+For details, see
+[The xPack GNU RISC-V Embedded GCC](https://xpack.github.io/riscv-none-embed-gcc/) pages.
+
+## Easy install
+
+The **xPack RISC-V Embedded GCC** toolchain is also available as a
+binary [xPack](https://www.npmjs.com/package/@xpack-dev-tools/riscv-none-embed-gcc)
+and can be conveniently installed with [xpm](https://www.npmjs.com/package/xpm):
+
+```console
+$ xpm install --global @xpack-dev-tools/riscv-none-embed-gcc@8.2.0-3.1.1
+```
+
+For more details on how to install the toolchain, please see
+[How to install the RISC-V toolchain?](http://xpack.github.io/toolchain/riscv-bone-embed-gcc/install/) page.
+
+## Compliance
+
+Starting with 8.2.0-2, the xPack GNU RISC-V Embedded GCC (formerly
+GNU MCU Eclipse RISC-V GCC) follows
+the official [SiFive releases](https://github.com/sifive/freedom-tools/releases),
+with as little differences as possible.
+
+This release is based on the
+[v2019.05.0](https://github.com/sifive/freedom-tools/releases/tag/v2019.05.0)
+release, and includes the SiFive extensions (like CLIC interrupts).
+
+The following commits (from [sifive/freedom-tools](https://github.com/sifive/freedom-tools/tree/master/src)) were used:
+
+- the [sifive/riscv-gcc](https://github.com/sifive/riscv-gcc) project,
+branch `sifive-gcc-8.2.0`, commit
+[242abcaff6](https://github.com/sifive/riscv-gcc/tree/242abcaff697d0a1ea12dccc975465e1bfeb8331)
+from from 5 April 2019
+- the [sifive/riscv-binutils-gdb](https://github.com/sifive/riscv-binutils-gdb)
+project, branch `sifive-binutils-2.32`, commit
+[164267155c](https://github.com/sifive/riscv-binutils-gdb/tree/164267155c96f91472a539ca78ac919993bc5b4e)
+from 28 February 2019
+- the [sifive/riscv-newlib](https://github.com/sifive/riscv-newlib) project,
+commit [42c2e3fb9f](https://github.com/sifive/riscv-newlib/tree/42c2e3fb9f557d59b76d1a64bb6fb32707ff4530)
+from 17 November 2018
+
+GDB was upstreamed and does not require SiFive specific patches,
+so the current build uses
+`git://sourceware.org/git/binutils-gdb.git`, the `9b40759` commit from
+28 Feb 2019.
+
+## Changes
+
+Compared to the original SiFive version, the **same architecture and API**
+options are supported, and there are minimal functional changes
+
+- `libgloss` was removed from the list of libraires always linked to the
+  application, since it issues `ECALL`
+  instructions that fail in bare metal environments
+- `march=rv32imaf/mabi=ilp32f` was added to the list of multilibs
+
+## newlib-nano
+
+Support for **newlib-nano** is available using the
+`--specs=nano.specs` option. For better results, this option must be
+added to both compile and link time.
+
+## nosys.specs
+
+If no syscalls are needed, `--specs=nosys.specs` can be used at link
+time to provide empty implementations for the POSIX system calls.
+
+## Compile options
+
+The libraries are compiled with `-O2 -mcmodel=medany`. The nano version is
+compiled with `-Os -mcmodel=medany`.
+
+> Important: It is mandatory for the applications to be compiled with
+`-mcmodel=medany`, otherwise the link will fail.
+
+## Documentation
+
+The original PDF documentation is available in the `share/doc` folder.
+
+## Support

+**GNU RISC-V Embedded GCC** toolchain.
+
+For details, see
+[The xPack GNU RISC-V Embedded GCC](https://xpack.github.io/riscv-none-embed-gcc/) pages.
+
+## Easy install
+
+The **xPack RISC-V Embedded GCC** toolchain is also available as a
+binary [xPack](https://www.npmjs.com/package/@xpack-dev-tools/riscv-none-embed-gcc)
+and can be conveniently installed with [xpm](https://www.npmjs.com/package/xpm):
+
+```console
+$ xpm install --global @xpack-dev-tools/riscv-none-embed-gcc@8.3.0-1.2.1
+```
+
+For more details on how to install the toolchain, please see
+[How to install the RISC-V toolchain?](http://xpack.github.io/toolchain/riscv-bone-embed-gcc/install/) page.
+
+## Compliance
+
+Starting with 8.2.0-2, the xPack GNU RISC-V Embedded GCC (formerly
+GNU MCU Eclipse RISC-V GCC) follows
+the official [SiFive releases](https://github.com/sifive/freedom-tools/releases),
+with as little differences as possible.
+
+This release is based on the
+[v2019.08.0](https://github.com/sifive/freedom-tools/releases/tag/v2019.08.0)
+release, and includes the SiFive extensions (like CLIC interrupts).
+
+The following commits (from [sifive/freedom-tools](https://github.com/sifive/freedom-tools/tree/master/src)) were used:
+
+- the [sifive/riscv-binutils-gdb](https://github.com/sifive/riscv-binutils-gdb)
+project, branch `sifive-binutils-2.32`, commit
+[03d23d5](https://github.com/sifive/riscv-binutils-gdb/tree/03d23d58701bdd425c613b0be2d458bcde46912b)
+from 2 September 2019
+- the [sifive/riscv-gcc](https://github.com/sifive/riscv-gcc) project,
+branch `sifive-gcc-8.3.0`, commit
+[e195042](https://github.com/sifive/riscv-gcc/tree/e195042babe2dc30d9fabb88d336d8c8679b3702)
+from from 7 Aug 2019
+- the [sifive/riscv-newlib](https://github.com/sifive/riscv-newlib) project, the `master` branch,
+commit [0d24a86](https://github.com/sifive/riscv-newlib/tree/0d24a86822a5ee73d6a6aa69e2a0118aa1e35204)
+from 9 July 2019
+
+GDB was upstreamed and does not require SiFive specific patches,
+so the current build uses
+`git://sourceware.org/git/binutils-gdb.git`, the `9b40759` commit from
+28 Feb 2019.
+
+## Changes
+
+Compared to the original SiFive version, the **same architecture and API**
+options are supported, and there are minimal functional changes
+
+- `libgloss` was removed from the list of libraires always linked to the
+  application, since it issues `ECALL`
+  instructions that fail in bare metal environments
+- `march=rv32imaf/mabi=ilp32f` was added to the list of multilibs
+
+## newlib-nano
+
+Support for **newlib-nano** is available using the
+`--specs=nano.specs` option. For better results, this option must be
+added to both compile and link time.
+
+## nosys.specs
+
+If no syscalls are needed, `--specs=nosys.specs` can be used at link
+time to provide empty implementations for the POSIX system calls.
+
+## Compile options
+
+The libraries are compiled with `-O2 -mcmodel=medany`. The nano version is
+compiled with `-Os -mcmodel=medany`.
+
+> Important: It is mandatory for the applications to be compiled with
+`-mcmodel=medany`, otherwise the link will fail.
+
+## Documentation
+
+The original PDF documentation is available in the `share/doc` folder.
+
+## Support
+
+For support, please read the
+[support](https://xpack.github.io/riscv-none-embed-gcc/support/) page.

+
+Common script used in other build scripts.
+
+- `host-functions-source.sh`: to be included with `source` in the host build script
+- `container-functions-source.sh`: to be included with `source` in the container build script
+
+Deprecated:
+
+- `builder-helper.sh`: used in the first generation of build scripts.
+
+# Patches
+
+The code used to download and extract archives can also be used
+to post-patch the downloaded files. For this a patch file must be
+placed in the `patches` folder, and the name must be passed as the
+third param to `extract()`.
+
+## Memo
+
+The code to apply the patch (`common-functions-source.sh:extract()`) does 
+the following:
+
+```console
+$ cd sources/binutils
+$ patch -p0 < "binutils-2.31.patch"
+```
+
+The patch is applied from the library source folder, so it must be created
+with the library relative path.
+
+For example, to create a binutils patch, use:
+
+```console
+$ cd sources/binutils
+$ cp bfd/ihex.c bfd/ihex-patched.c
+$ vi bfd/ihex-patched.c
+$ diff -u bfd/ihex.c bfd/ihex-patched.c > patches/binutils-2.31.patch
+```
+
+Alternatively, multiple changes can be generated by Git:
+
+```console
+$ git init
+$ git add -A
+$ git commit -m all
+```
+
+Perform changes as usual.
+
+To create a patch with the uncommitted changes that will be consumed
+with `patch`:
+
+```console
+$ git diff --no-prefix -u > file.patch
+```
+
+For completeness, to create a patch with the uncommitted changes that
+will be consumeed with `git apply file.git-patch`.
+
+```console
+$ git diff > file.git-patch
+```
+
+It is also possible to create patches with git and consume them with patch
+
+```console
+$ git diff --no-prefix -u > file.patch
+```

+This README file is copied into the directory for GCC-only header files
+when fixincludes is run by the makefile for GCC.
+
+Many of the files in this directory were automatically edited from the
+standard system header files by the fixincludes process.  They are
+system-specific, and will not work on any other kind of system.  They
+are also not part of GCC.  The reason we have to do this is because
+GCC requires ANSI C headers and many vendors supply ANSI-incompatible
+headers.
+
+Because this is an automated process, sometimes headers get "fixed"
+that do not, strictly speaking, need a fix.  As long as nothing is broken
+by the process, it is just an unfortunate collateral inconvenience.
+We would like to rectify it, if it is not "too inconvenient".

+
+	-1  indeterminate
+	 0  evaluate all operations and constants, whose semantic type has
+	    at most the range and precision of float, to the range and
+	    precision of float; evaluate all other operations and constants
+	    to the range and precision of the semantic type.
+	 1  evaluate all operations and constants, whose semantic type has
+	    at most the range and precision of double, to the range and
+	    precision of double; evaluate all other operations and constants
+	    to the range and precision of the semantic type.
+	 2  evaluate all operations and constants, whose semantic type has
+	    at most the range and precision of long double, to the range and
+	    precision of long double; evaluate all other operations and
+	    constants to the range and precision of the semantic type.
+	 N  where _FloatN  is a supported interchange floating type
+	    evaluate all operations and constants, whose semantic type has
+	    at most the range and precision of the _FloatN type, to the
+	    range and precision of the _FloatN type; evaluate all other
+	    operations and constants to the range and precision of the

+	    evaluate operations and constants, whose semantic type has at
