Pushed r14-5950 .. r14-5954 with minor change: a FSF copyright disclaimer is added into simd.md in the 1st patch, and an used match_scratch is removed from <simd_frint_pattern><mode>2 in the 5th patch. > Xi Ruoyao (5): > LoongArch: Fix usage of LSX and LASX frint/ftint instructions > [PR112578] > LoongArch: Use standard pattern name and RTX code for LSX/LASX muh > instructions > LoongArch: Use standard pattern name and RTX code for LSX/LASX rotate > shift > LoongArch: Remove lrint_allow_inexact > LoongArch: Use LSX for scalar FP rounding with explicit rounding mode > > gcc/config/loongarch/lasx.md | 283 ----------------- > gcc/config/loongarch/loongarch-builtins.cc | 52 ++-- > gcc/config/loongarch/loongarch.md | 12 +- > gcc/config/loongarch/lsx.md | 293 ------------------ > gcc/config/loongarch/simd.md | 268 ++++++++++++++++ > .../loongarch/vect-frint-no-inexact.c | 48 +++ > .../loongarch/vect-frint-scalar-no-inexact.c | 23 ++ > .../gcc.target/loongarch/vect-frint-scalar.c | 43 +++ > .../gcc.target/loongarch/vect-frint.c | 85 +++++ > .../loongarch/vect-ftint-no-inexact.c | 44 +++ > .../gcc.target/loongarch/vect-ftint.c | 83 +++++ > gcc/testsuite/gcc.target/loongarch/vect-muh.c | 36 +++ > .../gcc.target/loongarch/vect-rotr.c | 36 +++ > 13 files changed, 701 insertions(+), 605 deletions(-) > create mode 100644 gcc/config/loongarch/simd.md > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-frint-no-inexact.c > create mode 100644 > gcc/testsuite/gcc.target/loongarch/vect-frint-scalar-no-inexact.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-frint-scalar.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-frint.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-ftint-no-inexact.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-ftint.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-muh.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-rotr.c -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
