This patch support ssnpm, smnpm, smmpm, sspm and supm extensions[1]. To enable GCC to recognize and process ssnpm, smnpm, smmpm, sspm and supm extensions correctly at compile time.
[1]https://github.com/riscv/riscv-j-extension/blob/master/zjpm/instructions.adoc Changes for v4: - Fix the code based on the commit id 9b13bea07706a7cae0185f8a860d67209308c050. Changes for v3: - Fix the error messages in gcc/testsuite/gcc.target/riscv/arch-46.c Changes for v2: - Add the sspm and supm extensions. - Add the check_conflict_ext function to check the compatibility of ssnpm, smnpm, smmpm, sspm and supm extensions. - Add the test cases for ssnpm, smnpm, smmpm, sspm and supm extensions. gcc/ChangeLog: * common/config/riscv/riscv-common.cc (riscv_subset_list::check_conflict_ext): New extension. * config/riscv/riscv.opt: Ditto. gcc/testsuite/ChangeLog: * gcc.target/riscv/arch-49.c: New test. * gcc.target/riscv/arch-50.c: New test. --- gcc/common/config/riscv/riscv-common.cc | 36 ++++++++++++++++++++++++ gcc/config/riscv/riscv.opt | 19 +++++++++++++ gcc/testsuite/gcc.target/riscv/arch-49.c | 5 ++++ gcc/testsuite/gcc.target/riscv/arch-50.c | 10 +++++++ 4 files changed, 70 insertions(+) create mode 100644 gcc/testsuite/gcc.target/riscv/arch-49.c create mode 100644 gcc/testsuite/gcc.target/riscv/arch-50.c diff --git a/gcc/common/config/riscv/riscv-common.cc b/gcc/common/config/riscv/riscv-common.cc index ca14eb96b253..0039833ad3e4 100644 --- a/gcc/common/config/riscv/riscv-common.cc +++ b/gcc/common/config/riscv/riscv-common.cc @@ -259,6 +259,10 @@ static const riscv_implied_info_t riscv_implied_info[] = {"ssstateen", "zicsr"}, {"sstc", "zicsr"}, + {"ssnpm", "zicsr"}, + {"smnpm", "zicsr"}, + {"smmpm", "zicsr"}, + {"xsfvcp", "zve32x"}, {NULL, NULL} @@ -445,6 +449,12 @@ static const struct riscv_ext_version riscv_ext_version_table[] = {"sstc", ISA_SPEC_CLASS_NONE, 1, 0}, {"ssstrict", ISA_SPEC_CLASS_NONE, 1, 0}, + {"ssnpm", ISA_SPEC_CLASS_NONE, 1, 0}, + {"smnpm", ISA_SPEC_CLASS_NONE, 1, 0}, + {"smmpm", ISA_SPEC_CLASS_NONE, 1, 0}, + {"sspm", ISA_SPEC_CLASS_NONE, 1, 0}, + {"supm", ISA_SPEC_CLASS_NONE, 1, 0}, + {"svade", ISA_SPEC_CLASS_NONE, 1, 0}, {"svadu", ISA_SPEC_CLASS_NONE, 1, 0}, {"svinval", ISA_SPEC_CLASS_NONE, 1, 0}, @@ -1347,6 +1357,26 @@ riscv_subset_list::check_conflict_ext () error_at (m_loc, "%<-march=%s%>: zcf extension supports in rv32 only", m_arch);
