The patch series add loongarch32 and ilp32 abi support to gcc. One can build libgcc, libatomic and glibc etc and generate a complete loongarch32-unknown-linux-gnu-toolchain with minimal patches at:
- binutils: https://github.com/jiegec/binutils-gdb/tree/loongarch32 - glibc: https://github.com/jiegec/glibc/tree/loongarch32 - crosstool-ng: https://github.com/jiegec/crosstool-ng/tree/loongarch32 We will wait for folks at Loongson to complete abi documentation of ilp32d abi. Changes since v1: - Can build a complete toolchain with glibc - Fix sizeof(long double) in ilp32 abi - Fix ftintrz generation for loongarch32 Full changes: Jiajie Chen (14): LoongArch: Introduce loongarch32 target LoongArch: Fix default ISA setting LoongArch: Fix SI division for loongarch32 target LoongArch: Fix movgr2frh.w operand order LoongArch: Fix 64-bit move for loongarch32 target LoongArch: Fix 64-bit immediate move for loongarch32 target LoongArch: Fix signed 32-bit overflow for loongarch32 target LoongArch: Disable SF/DF -> unsigned DI expand in loongarch32 LoongArch: Add -march=loongarch64 to tests with -mabi=lp64d LoongArch: Forbid ADDRESS_REG_REG in loongarch32 LoongArch: Mark am* instructions as LA64-only LoongArch: Set long double width to 128 in la32 LoongArch: Fix ilp32 detection LoongArch: Allow ftintrz for DF->DI in loongarch32 contrib/config-list.mk | 1 + gcc/config.gcc | 61 ++++++++++++++++--- .../loongarch/genopts/loongarch-strings | 5 ++ gcc/config/loongarch/genopts/loongarch.opt.in | 12 ++++ gcc/config/loongarch/gnu-user.h | 3 + gcc/config/loongarch/linux.h | 8 ++- gcc/config/loongarch/loongarch-c.cc | 12 ++++ gcc/config/loongarch/loongarch-def.c | 33 ++++++++++ gcc/config/loongarch/loongarch-def.h | 25 +++++--- gcc/config/loongarch/loongarch-driver.h | 4 ++ gcc/config/loongarch/loongarch-opts.cc | 27 ++++++-- gcc/config/loongarch/loongarch-opts.h | 20 ++++-- gcc/config/loongarch/loongarch-str.h | 5 ++ gcc/config/loongarch/loongarch.cc | 7 ++- gcc/config/loongarch/loongarch.h | 2 +- gcc/config/loongarch/loongarch.md | 39 ++++++------ gcc/config/loongarch/loongarch.opt | 12 ++++ gcc/config/loongarch/sync.md | 10 +-- gcc/config/loongarch/t-linux | 16 ++++- gcc/testsuite/g++.target/loongarch/bytepick.C | 2 +- gcc/testsuite/g++.target/loongarch/pr106828.C | 2 +- .../gcc.target/loongarch/add-const.c | 2 +- gcc/testsuite/gcc.target/loongarch/arch-1.c | 5 ++ gcc/testsuite/gcc.target/loongarch/arch-2.c | 5 ++ .../gcc.target/loongarch/array-ldx.c | 6 ++ .../gcc.target/loongarch/attr-model-1.c | 2 +- .../gcc.target/loongarch/attr-model-2.c | 2 +- .../gcc.target/loongarch/flt-abi-isa-1.c | 2 +- gcc/testsuite/gcc.target/loongarch/fscaleb.c | 2 +- .../gcc.target/loongarch/ftint-no-inexact.c | 2 +- gcc/testsuite/gcc.target/loongarch/ftint.c | 2 +- .../gcc.target/loongarch/func-call-1.c | 2 +- .../gcc.target/loongarch/func-call-2.c | 2 +- .../gcc.target/loongarch/func-call-3.c | 2 +- .../gcc.target/loongarch/func-call-4.c | 2 +- .../gcc.target/loongarch/func-call-5.c | 2 +- .../gcc.target/loongarch/func-call-6.c | 2 +- .../gcc.target/loongarch/func-call-7.c | 2 +- .../gcc.target/loongarch/func-call-8.c | 2 +- .../loongarch/func-call-extreme-1.c | 2 +- .../loongarch/func-call-extreme-2.c | 2 +- .../gcc.target/loongarch/func-call-medium-1.c | 2 +- .../gcc.target/loongarch/func-call-medium-2.c | 2 +- .../gcc.target/loongarch/func-call-medium-3.c | 2 +- .../gcc.target/loongarch/func-call-medium-4.c | 2 +- .../gcc.target/loongarch/func-call-medium-5.c | 2 +- .../gcc.target/loongarch/func-call-medium-6.c | 2 +- .../gcc.target/loongarch/func-call-medium-7.c | 2 +- .../gcc.target/loongarch/func-call-medium-8.c | 2 +- gcc/testsuite/gcc.target/loongarch/imm-load.c | 2 +- .../gcc.target/loongarch/imm-load1.c | 2 +- gcc/testsuite/gcc.target/loongarch/mulw_d_w.c | 2 +- .../gcc.target/loongarch/pr109465-1.c | 2 +- .../gcc.target/loongarch/pr109465-2.c | 2 +- .../gcc.target/loongarch/pr109465-3.c | 2 +- .../gcc.target/loongarch/prolog-opt.c | 2 +- .../loongarch/relocs-symbol-noaddend.c | 2 +- .../loongarch/zero-size-field-pass.c | 2 +- .../loongarch/zero-size-field-ret.c | 2 +- libitm/config/loongarch/asm.h | 2 +- 60 files changed, 298 insertions(+), 96 deletions(-) create mode 100644 gcc/testsuite/gcc.target/loongarch/arch-1.c create mode 100644 gcc/testsuite/gcc.target/loongarch/arch-2.c create mode 100644 gcc/testsuite/gcc.target/loongarch/array-ldx.c -- 2.41.0
