Paul Khuong e18fba64ec gcc/x86{,_64}/ck_pr: improve codegen for compare-and-swap, particularly on GCC6+ ... 1. For ck_pr_cas_foo_value, let the inline assembly save the observed value in a register, and store to the output reference in C. This lets the C optimiser eliminate the memory access once the CAS function is inlined. 2. Specify the result of the CAS as a condition code in EFLAGS instead of executing SETcc in inline assembly, when possible. GCC gained this functionality in GCC 6; CAS loops can now directly branch on the condition code, without SETcc / TEST. TESTED=existing regression tests.		5 years ago
