The libm size improvement built with "--enable-stack-protector=strong --enable-bind-now=yes --enable-fortify-source=2": Before: text data bss dec hex filename 585192 860 12 586064 8f150 aarch64-linux-gnu/math/libm.so 960775 1068 12 961855 ead3f x86_64-linux-gnu/math/libm.so 1189174 5544 368 1195086 123c4e powerpc64le-linux-gnu/math/libm.so After: text data bss dec hex filename 584952 860 12 585824 8f060 aarch64-linux-gnu/math/libm.so 960615 1068 12 961695 eac9f x86_64-linux-gnu/math/libm.so 1189078 5544 368 1194990 123bee powerpc64le-linux-gnu/math/libm.so The are small code changes for x86_64 and powerpc64le, which do not affect performance; but on aarch64 with gcc-14 I see a slight better code generation due the usage of ldq for floating point constant loading.
