L. Pereira	7badd2d5b2	Set _XOPEN_SOURCE when building on Darwin ... On non-freestanding builds, including <ucontext.h> on an ARM Darwin system will produce the following error: In file included from include/libucontext/bits.h:6: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/ usr/include/ucontext.h:51:2: error: The deprecated ucontext routines require _XOPEN_SOURCE to be defined Defining this macro on Darwin systems will make the building pass.	2024-08-07 17:49:36 -07:00

Jim Hauxwell	b3cbfd9c1a	fix parallel build for makefile ... The copy for bits.h ran in parallel with the initial CC. sometimes on CI the build would fail as the file had not arrived by the time needed. Fix matches meson build process.	2024-08-07 17:48:29 -07:00
Sören Tempel	d0b03541bf	common-trampoline: Ensure omission of frame-pointer ... Some architecture-specific implementations of the FETCH_LINKPTR (e.g. the one for x86) attempt to find the linkptr relative to the stack pointer. Therefore, they make assumption about the value of the SP at the point where the FETCH_LINKPTR code is executed. This means that we don't want the C compiler to mess with our SP. For this purpose, local variables in this function are currently declared using the register storage specifier. Additionally, we need to make sure that a frame pointer is /always/ omitted for this function. On x86 Alpine, the frame pointer is presently not omitted with GCC 13 when using -Os, therefore the tests segfault with -Os on Alpine presently. Fixes #52	2024-08-07 17:46:50 -07:00
Volker Christian	124a962b39	aarch64: fix return value if getcontext was used to acquire the current context. ... x0 hast to be 0 in case setcontext is called with a context acquired by getcontext. Thus x0=0 must be stored in getcontext.	2024-08-07 17:45:47 -07:00
Volker Christian	9e5de65076	libucontext: Add patch fixing return values of get/set/swapcontext ... The arm ABI defines that the value in register r0 is used as the return value of a function. To indicate success for get/set/swapcontext (return value of 0) the register r0 must contain zero at the end of the function call. Thus set r0 to zero and store it in the context. This context is restored later and indicate successful execution, because r0 is 0. The order registers are stored has changed so that only one additional instruction (mov r0, #0) needs to be added to fix the return value bug for get/set/swapcontext.

Volker Christian	076e69c9c1	libucontext: Add error checking ... Add error checking test_libucontext and test_libucontext_posix to test return values of get/set/swapcontext.

matoro	be80075e95	meson: support building docs ... Toggleable with -Ddocs=(true|false), defaults to false. Requires bumping minimum meson version to 0.59.0, or 0.61.0 to also include symlinks.	2023-05-18 18:12:55 -07:00

L. Pereira	0f625a86ee	Fix FREESTANDING install target ... When installing a FREESTANDING build, the check for an empty variable was not being honored because the empty string would evaluate to nothing.
