Changes from 1.3.1 to 1.3.2
---------------------------
* Rewrite makecontext in C on LoongArch.
* Fix building x86 and loongarch64 variants on Meson.
Patch by Volker Christian.
Changes from 1.3 to 1.3.1
-------------------------
* Disable hard-float support on ARM by default.
* Fix up getcontext/swapcontext return values on LoongArch.
* Fix assembler warnings when building on LoongArch.
Changes from 1.2 to 1.3
-----------------------
* Fix up getcontext/swapcontext return values across a few ports.
Patches contributed for ARM and test suite by Volker Christian.
* Add support for hard-float on ARM.
Patches contributed by Richard Campbell.
* Align build system variables with those used by Automake.
Patch contributed by Ismael Luceno.
* Fix sporadic parallel build failures.
Patches contributed by Jim Hauxwell.
* Ensure frame pointers are omitted when using the C trampoline.
Patch contributed by Sören Tempel.
* Define _XOPEN_SOURCE when building on Darwin.
Patch contributed by L. Pereira.
* Add support for building the manpages with Meson.
Patch contributed by matoro.
* Migrate build from _BSD_SOURCE to _DEFAULT_SOURCE.
Changes from 1.1 to 1.2
-----------------------
* Added Loongarch64 port.
* Added OpenRISC (or1k) port.
* Fixed various build system issues:
- libucontext_posix.so is no longer underlinked
- Executable stacks are now disabled when using GNU-like toolchains
- CPPFLAGS is used consistently
- Users may now build on Darwin without using Meson
* aarch64 now implements the necessary SIMD register save/restore as
mandatory in AAPCS64.
Patches contributed by Richard Campbell.
Changes from 1.0 to 1.1
-----------------------
* Added RISC-V RV32 port.
* Cleaned up use of _GNU_SOURCE in C code.
Partially from patches contributed by osy.
* Added automatic detection of armv7l architecture.
Patch contributed by Leandro Pereira.
* Fixed installation path of libucontext_posix.a.
* Work around deficiency in clang built-in assembler on AArch64 targets.
Patch contributed by osy.
Changes from 0.13.1 to 1.0
--------------------------
* Implement common libucontext_trampoline, written in C with inline
assembly.
* Added Renesas / Hitachi SH-2/SH-4 port (sh).
* Added Meson build system, primarily for the convenience of using
libucontext with qemu as a subproject.
* Added support for Mach-O ABI.
* Fixed deficiencies in libucontext ABI, SONAME has been bumped due
to the ABI regressions in 0.13.
Changes from 0.13 to 0.13.1
---------------------------
* Fix installation of libucontext.pc.
Patch contributed by Ömer Faruk IRMAK.
Changes from 0.12 to 0.13
-------------------------
* Aligned RISC-V RV64 port's header usage with musl 1.2 to remove
warnings and ensure consistent register name usage.
* Added Motorola 680X0 / NXP ColdFire port (m68k).
* Added support for building for bare-metal targets with newlib via
make FREESTANDING=yes. Other OS are also supported (for example,
the m68k freestanding port was tested on AmigaOS), PowerPC requires
kernel assistance and cannot be built with FREESTANDING=yes. Not
all ports have support for FREESTANDING yet, patches welcome.
Changes from 0.11 to 0.12
-------------------------
* Fixed compilation of RISC-V RV64 port with modern musl releases.
Changes from 0.10 to 0.11
-------------------------
* Added RISC-V RV64 port.
* Fixed compilation with clang.
Patch contributed by Khem Raj.
* Add ${LIBDIR} variable to build system.
Patch contributed by Khem Raj.
Changes from 0.9.0 to 0.10
--------------------------
* Added MIPS O32 and MIPS N64 ports.
MIPS N32 ABI is theoretically supported by ARCH=mips64 with
a MIPS N32 toolchain, but this has not been tested.
* Improved test program (test_libucontext) verbosity.
* Modernized all architectures to use common assembly
macros, such as REG_OFFSET(reg), FUNC() and ALIAS().
* Added debugging hints to assembly functions for GDB.
* Automatically alias i386/i686 to x86 in makefile.
Patch contributed by Gabriel Ivascu.
Changes from 0.1.3 to 0.9.0
---------------------------
* Pass ${LDFLAGS} when linking the libucontext library.
Patch contributed by Khem Raj.
* Fix clobbering of the first stack argument on x86.
Patch contributed by A. Wilcox.
* Add support for building a static libucontext.
Patches contributed by Gabriel Ivascu.
* Rewrite ppc/ppc64 implementation to fully use the
swapcontext(3) syscall.
Patches contributed by Bobby Bingham.
Changes from 0.1.1 to 0.1.3
---------------------------
* Fix register clobbering on x86_64.
Patches contributed by A. Wilcox and Timo Teräs.
Changes from 0.1.0 to 0.1.1
---------------------------
* Added S390X port.
* Cleaned up the ppc/ppc64 trampoline.
* Fixed up GOT clobbering and removed a textrel from the x86
trampoline.
