Merge pull request #27 from utmapp/qemu-support-v2 
Remaining fixes for Apple Silicon and QEMU
 2021-03-08 20:48:30 -06:00
osy 9b1d8f01a6 aarch64: remove usage of FUNC macro for clang 
Clang's arm64 assembler does not support multiple directives on a single
line. C macros ALWAYS expand to a single line.

osy 5d66c194a7 x86_64: define reg names if not defined 
_GNU_SOURCE can be defined without defining REG_X macros so it is not a
good indicator. (QEMU for example defines it in the build system.) x86
and x86_64 should have consistant looking defs.h so ifndef guards are
added to each REG_X definition.

osy f3e1b876c7 project: move freestanding include headers 
This is needed because in libucontext.h we include "libucontext/bits.h".
We therefore need to have bits.h in somepath/libucontext/bits.h. In the
Makefile, somepath/freestanding/bits.h was copied to the right path but
in the meson build system, the include copy happens at the end.

Merge pull request #26 from lpereira/armv7l-makefile-fix 
Fix ARCH deduction on armv7l when using Makefiles
 2021-02-05 11:46:37 -07:00
Leandro Pereira 7823593b6f Fix ARCH deduction on armv7l when using Makefiles 
The Makefile on ARMv7l devices (e.g. Raspberry Pi 400 running the
stock Raspbian distro) was failing to deduct the architecture and
empty libraries were being built as a result.  Building with Meson
works fine; only building with make generated empty libraries.

Add an override for armv7l -> arm in the Makefile to address this.

Merge pull request #25 from q66/ppc-no-alias 
fix ALIAS usage in ppc, fix meson build, hide libucontext_trampoline
 2021-01-08 09:59:47 -05:00
Daniel Kolesa f3e0033a06 meson: remove the subproject-based library checking 
this is not idiomatic, and should not be done (and it did not even
work in the first place); meson is capable of building both
libraries via library() and then you can choose on commandline

it defaults to only shared, but we want both out of box, so specify
that

ppc, ppc64: tag global symbols as functions
 2021-01-08 04:23:59 -05:00
Daniel Kolesa cf05112306 ppc, ppc64: use common ALIAS/FUNC/END macros 2021-01-08 04:52:46 +01:00
Daniel Kolesa 6026980cac ppc, ppc64: tag global symbols as functions 
it is necessary to tag these symbols as functions otherwise the
linker gets confused; this previously manifested as the internal
functions (pre-rename) like __getcontext leaking into the symbol
table of things linked against libucontext that used the ucontext
POSIX API through the weak aliases

it also had another bad effect and that is if you tried to use
libucontext's API (post-rename), the linker would warn you during
compile time that the type is unknown, and the resulting program
would crash at runtime

after properly tagging everything, I no longer notice any leakage,
i.e. there don't seem to be any references to the aliased symbols
in the resulting symbol table when using the aliases, and using
the libucontext prefixed symbols directly also works

Daniel Kolesa 03927d4c4c build: depend on headers for the static target
