This is an update of https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628772.htmlChanges since the last patchset: 1. Fix texinfo format of the install.texi document. 2. Add documentation for --with-strict-align-lib. v1 -> v2: 1. Add new configure option --with-strict-align-lib to control whether -mstrict-align should be used when building libraries. This facilitates building toolchains targeting both LA264 (Loongson 2k1000la) and non-LA264 cores. 2. Define preprocessing macros __loongarch_sx / __loongarch_asx / __loongarch_simd_width that indicates the enabled SIMD extensions. 3. Keep the current non-symmetric multidir layout, but do not build duplicate multilib variants with the same ABI option. Make --with-abi= obsolete to ensure a consistent directory layout. (ABI type of the "toplevel" libraries can be inferred from the target triplet) 4. Using "-mno-lasx" do not cause a fallback to "-msimd=none" as long as the -march= architecture or the default --with-simd= setting has LSX support.
