[PATCH v2 11/14] LoongArch: Mark am* instructions as LA64-only

LoongArch32 only provides basic ll/sc instructions for atomic operations. Mark am* atomic instructions as 64-bit only. gcc/ChangeLog: * config/loongarch.sync.md: Guard am* atomic insns by TARGET_64BIT. --- gcc/config/loongarch/sync.md | 10 +- 1 file changed, 5 insertions

[PATCH v2 14/14] LoongArch: Allow ftintrz for DF->DI in loongarch32

In LoongArch, signed DF->DI conversion can be done if -mfpu=64 and -march=loongarch32. gcc/ChangeLog: * config/loongarch/loongarch.md (fix_trunc*2): Use ANYFI instead of GPR because it depends on fpu width instead of target bits. --- gcc/config/loongarch/loongarch.md | 8

[PATCH v2 10/14] LoongArch: Forbid ADDRESS_REG_REG in loongarch32

LoongArch32 does not include LDX/STD instructions, and cannot lower (plus (reg) (reg)) pattern. Forbid ADDRESS_REG_REG and do not emit ldx/stx. gcc/ChangeLog: * config/loongarch/loongarch.cc (loongarch_valid_index_p): Check ADDRESS_REG_REG pattern and fail in loongarch32.

[PATCH v2 08/14] LoongArch: Disable SF/DF -> unsigned DI expand in loongarch32

The current SF/DF -> unsigned DI expand rules require iordi3 insn which is not available in loongarch32. gcc/ChangeLog: * config/loongarch/loongarch.md (fixuns_truncdfdi2): Add TARGET_64BIT to condition. (fixuns_truncsfdi2): Add TARGET_64BIT to condition. --- gcc/config/l

[PATCH v2 06/14] LoongArch: Fix 64-bit immediate move for loongarch32 target

loongarch_move_integer does not support splitting 64-bit integer into two 32-bit ones. Thus, define_split is removed from movdi_32bit and TARGET_64BIT is added to the split condition of movdi_64bit to avoid using it for loongarch32. gcc/ChangeLog: * config/loongarch/loongarch.md (movdi_32

[PATCH v2 12/14] LoongArch: Set long double width to 128 in la32

According to latest loongarch procedure call standard, sizeof(long double) == 128 in ilp32 data model regardless of target bitness. gcc/ChangeLog: * config/loongarch/loongarch.h: Set LONG_DOUBLE_TYPE_SIZE to 128 regardless of target bitness. --- gcc/config/loongarch/loongarch.h |

[PATCH v2 01/14] LoongArch: Introduce loongarch32 target

Introduce loongarch32 target and ilp32 abi variants. The ilp32d abi variant is selected as the default abi of loongarch32 target. Currently, ilp32 abi can only be used for loongarch32, but in the future, it might be possible to use ilp32 abi for loongarch64. contrib/ChangeLog: * config-l

[PATCH v2 04/14] LoongArch: Fix movgr2frh.w operand order

The operand order of movgr2frh.w was wrong. The correct order should be `movgr2frh.w fd, rj`. gcc/ChangeLog: * config/loongarch/loongarch.md (movgr2frh): Correct movgr2frh.w operand order. --- gcc/config/loongarch/loongarch.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

[PATCH v2 02/14] LoongArch: Fix default ISA setting

When loongarch_arch_target is called, la_target has not been initialized, thus the macro LARCH_ACTUAL_ARCH always equals to zero. This commit fixes by expanding the macro and reading the latest value. It permits -march=loongarch64 when the default target is loongarch32 and vice versa. gcc/ChangeL
