This may improve lock scaling of existing programs on + HTM capable systems. The lock elision code is only enabled with + --enable-lock-elision=yes. Also, the TSX lock elision implementation for + powerpc will issue a transaction abort on every syscall to avoid side + effects being visible outside transactions. + * Optimized strcpy, stpcpy, strchrnul and strrchr implementations for AArch64.
