2021-09-01Fix arm target build with inhibit_libcSebastian Huber1-4/+0
Do not declare abort in "libgcc/unwind-arm-common.inc" since it is already provided by "tsystem.h". It fixes the following build error: In file included from libgcc/config/arm/unwind-arm.c:144: libgcc/unwind-arm-common.inc:55:24: error: macro "abort" passed 1 arguments, but takes just 0 55 | extern void abort (void); libgcc/ * unwind-arm-common.inc (abort): Remove.

2020-02-10arm: Fix up arm installed unwind.h for use in pedantic modes [PR93615]Christophe Lyon1-4/+4
Commit r10-6500-g811a475ea3fcc55ee4aea7c81171891ef19dfc25 broke the GCC build for arm-none-uclinuxfdpiceabi, as it forgot to update some uses of gnu_Unwind_Find_got. 2020-02-10 Christophe Lyon <christophe.lyon@linaro.org> libgcc/ PR target/93615 * unwind-arm-common.inc: Replace uses of gnu_Unwind_Find_got with _Unwind_gnu_Find_got. * unwind-pe.h: Likewise.

2019-09-10[ARM/FDPIC v6 06/24] [ARM] FDPIC: Add support for c++ exceptionsChristophe Lyon1-0/+94
The main difference with existing support is that function addresses are function descriptor addresses instead. This means that all code dealing with function pointers now has to cope with function descriptors instead. For the same reason, Linux kernel helpers can no longer be called by dereferencing their address, so we implement wrappers that directly call the kernel helpers. When restoring a function address, we also have to restore the FDPIC register value (r9). 2019-09-10 Christophe Lyon <christophe.lyon@st.com> Mickaël Guêné <mickael.guene@st.com> gcc/ * ginclude/unwind-arm-common.h (unwinder_cache): Add reserved5 field. libgcc/ * config/arm/linux-atomic.c (__kernel_cmpxchg): Add FDPIC support.
