Subject: [PATCH 0/4] LoongArch: target configuration interface update
Date: Wed, 30 Aug 2023 09:58:04 +0800 [thread overview]
Message-ID: <20230830015808.19870-1-yangyujie@loongson.cn> (raw)
This is an update of
https://gcc.gnu.org/pipermail/gcc-patches/2023-August/627275.html
Changes since the last patchset:
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.
5. Other bug fixes.
Yang Yujie (4):
LoongArch: improved target configuration interface
LoongArch: define preprocessing macros "__loongarch_{arch,tune}"
LoongArch: add new configure option --with-strict-align-lib
LoongArch: support loongarch*-elf target
