Hi all, This single commit patch is intended to add initial support for RV64E and LP64E ABI.
Following the discussion at: <https://github.com/riscv-non-isa/riscv-c-api-doc/pull/52>, "__riscv_64e" preprocessor macro will be a part of the RISC-V C API Specification, I will submit this patch as non-RFC. As invoke.texi states that RVE ABIs are subject to change so I consider that the fact that the RVE ABIs are not ratified will not block merging the changes. Previous RFC PATCH: <https://gcc.gnu.org/pipermail/gcc-patches/2023-October/633846.html> Thanks, Tsukasa Tsukasa OI (1): RISC-V: Initial RV64E and LP64E support gcc/common/config/riscv/riscv-common.cc | 8 +-- gcc/config.gcc | 10 ++-- gcc/config/riscv/arch-canonicalize | 2 +- gcc/config/riscv/riscv-c.cc | 3 +- gcc/config/riscv/riscv-d.cc | 1 + gcc/config/riscv/riscv-opts.h | 1 + gcc/config/riscv/riscv.cc | 19 ++++--- gcc/config/riscv/riscv.h | 17 ++++-- gcc/config/riscv/riscv.opt | 3 ++ gcc/doc/invoke.texi | 7 +-- gcc/testsuite/gcc.target/riscv/predef-1.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-2.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-3.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-4.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-5.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-6.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-7.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-8.c | 3 ++ gcc/testsuite/gcc.target/riscv/predef-9.c | 66 +++++++++++++++++++++++ 19 files changed, 137 insertions(+), 24 deletions(-) create mode 100644 gcc/testsuite/gcc.target/riscv/predef-9.c base-commit: e377a340b34de1b06f2825691e45a33affcb4c2d -- 2.42.0
