========== LEON Linux 5.10 Toolchain 2.3 ==========

Linux kernel headers from 5.10.258, matching our kernel release LEON
Linux 5.10-1.11.

GLIBC:
- Rebase on top of the latest upstream GLIBC 2.39 branch

The toolchain is based on GCC 13.2.1 and GLIBC 2.39.

========== LEON Linux 5.10 Toolchain 2.2 ==========

Linux kernel headers from 5.10.246, matching our kernel release LEON
Linux 5.10-1.10.

The toolchain is based on GCC 13.2.1 and GLIBC 2.39.

========== LEON Linux 5.10 Toolchain 2.1 ==========

Linux kernel headers from 5.10.237, matching our kernel release LEON
Linux 5.10-1.9.

The toolchain is based on GCC 13.2.1 and GLIBC 2.39.

GCC:
- Use DWARF version 4 instead of 5
- Ignore empty instruction in UT699 errata workaround

GLIBC:
- Rebase on top of the latest upstream GLIBC 2.39 branch
- Fix race conditions in pthread cancellation
- Fix syscall_cancel for LEON
- Fix restartable syscalls
- Mitigation for "clone on sparc might fail with -EFAULT for no valid reason"

========== LEON Linux 5.10 Toolchain 2.0 ==========

Linux kernel headers from 5.10.214, matching our kernel release LEON
Linux 5.10-1.6.

The toolchain is based on GCC 13.2 and GLIBC 2.39.

GCC:
- Rebase on top of latest upstream GCC master branch (13.2)
  - Based on commit: e3d4ebdc67ccb376916e140322d968571d114d18
- Added support for address and undefined behaviour sanitizers.

GLIBC:
- Rebase on top of the latest upstream GLIBC 2.39 branch
- Configured with --default-no-pie as it otherwise leads to issues when
  starting programs linked with the -pie option [1].
- Configured with --enable-bind-now to disable dynamic linking as it
  otherwise might fail on SMP systems.

binutils:
- Updated to version 2.42

GDB:
- Updated to version 14.2

========== LEON Linux 5.10 Toolchain 1.4 ==========

Linux kernel headers from 5.10.169, matching our kernel release LEON
Linux 5.10-1.4.

Add LEON5 multilib with -mcpu=leon5.

GLIBC:
- Rebase on top of the latest upstream GLIBC 2.31 branch
- Prevent stfsr from directly following floating-point instruction in
  accordance with TN-0016
- Add additional fix for TN-0009 errata for stfsr
- Force FPU exceptions to happen without delay when calling feraiseexcept
- Add fix for inexact/invalid exception bits for converting out of
  range floats to integers

Make sure that a store-load memory barrier generated by GCC flushes
entire writebuffer on LEON5, regardless of -mcpu.

========== Cobham Gaisler Linux 5.10 Toolchain 1.3 ==========
