If the stack frame only contains an alloca area, then
pdp11_expand_epilogue fails to deallocate it, resulting
in callee-saved registers and the return address being
restored from the wrong stack slots. Fixed by adding
|| cfun->calls_alloca to the condition for deallocating
the frame.

PR target/105525 is a build regression for the vax and lm32 linux
targets present in gcc-12/13/head, where the builds fail due to
unsatisfied references to __INTPTR_TYPE__ and __UINTPTR_TYPE__,
caused by these two targets failing to provide glibc-stdint.h.
Fixed thusly, tested by building crosses,

PR98860 is a gcc-11 regression where bootstrap fails on Windows since
the switch to enable DWARF5 by default. The symptoms are that
executables generated by the stage1 compiler fail to run with "Exec
format error", which confuses subsequent configure steps and causes
hard errors. This happens even

This fixes the bootstrap failure with Ada on Cygwin since the switch
to C++11. The configure checks detect that fileno_unlocked () is
present, but when Ada's cstreams.c is compiled in C++11 mode,
does not declare it, causing a hard error.
Fixed by defining _GNU_SOURCE before including .

This fixes a compilation error preventing bootstrap with Ada on
x86_64-pc-cygwin. See PR bootstrap/94918 for details.
Compared to the initial patch sent in May 2020, this v2 patch places
the fix in Ada's raise-gcc.c instead of the shared unwind-generic.h,
which should hopefully simplify getting it

This fixes three compilation errors preventing bootstrap of gcc-10/11
with Ada on x86_64-pc-cygwin. See PR bootstrap/94918 for details.
Tested by bootstrapping on x86_64-pc-cygwin, and since it touches code
shared with mingw, also by building a cross to x86_64-w64-mingw32.
Ok for master and gcc-
14 matches
