Commit Message

Fix AO_compare_and_swap_full asm code for clang on sparc

Issue #52 (libatomic_ops).

The issue (SIGSEGV in test_malloc) is observed with clang-13, at least.
The workaround is to simplify asm code of AO_compare_and_swap_full
(moving the comparison of CAS result and old value to C code).

* src/atomic_ops/sysdeps/gcc/sparc.h [(!(AO_GNUC_PREREQ(12,0)
|| AO_CLANG_PREREQ(13,0)) || AO_DISABLE_GCC_ATOMICS) && !AO_NO_SPARC_V9
&& !AO_GENERALIZE_ASM_BOOL_CAS] (AO_compare_and_swap_full): Remove ret
local variable; remove cmp, be, mov, clr instructions from asm block
(to match that of AO_fetch_compare_and_swap_full); remove cc from asm
block clobbers; change specifier for old input operand of asm block
(from "0" to "r"); return new_val==old instead of ret.
