libucontext with qemu as a subproject.

|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
* 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).
|
|
|
|
|

2020-12-06 10:30:13 +00:00
|
|
|
* 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
|
2020-12-06 10:45:05 +00:00
|
|
|
kernel assistance and cannot be built with FREESTANDING=yes. Not
|
|
|
|
|
all ports have support for FREESTANDING yet, patches welcome.

|
2020-03-30 06:38:23 +00:00
|
|
|
MIPS N32 ABI is theoretically supported by ARCH=mips64 with
|
|
|
|
|
a MIPS N32 toolchain, but this has not been tested.
|
2020-03-30 06:36:08 +00:00

|
|
|
* 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.
|
|
|
