Michael Munday	e28b6a60bc	[RISCV][NFC] Regenerate RISCV CodeGen tests ... Regenerated using: ./llvm/utils/update_llc_test_checks.py -u llvm/test/CodeGen/RISCV/*.ll This has added comments to spill-related instructions and added @plt to some symbols.

Craig Topper	ce5f4f22e9	[RISCV] Use the 'si' lib call for (double (fp_to_sint/uint i32 X)) when F extension is enabled. ... D80526 added custom lowering to pick the si lib call on RV64, but this custom handling is only enabled when the F and D extension are both disabled. This prevents the si library call from being used for double when F is enabled but D is not. This patch changes the behavior so we always enable the Custom hook on RV64 and decide in ReplaceNodeResults if we should emit a libcall based on whether the FP type should be softened or not.

Craig Topper	574de837d4	Recommit "[RISCV] Move some test cases from rv64i-single-softfloat.ll to a new rv64i-double-softfloat.ll. NFC"" ... With new test file this time. Original message This new test covers both with and without the F extension enabled. This shows that the fptosi/fptoui for double->i32 use a different libcall depending on whether the F extension is enabled. If it's not enabled we use the 'si' library call. If it is enabled we use 'di'.	2020-11-04 19:58:11 -08:00
