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.
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.
