Supported formats include: + * `arch=<arch>` strings - specifies architecture features for a function (equivalent to `-march=<arch>`). + * `tune=<cpu>` strings - specifies the tune CPU for a function (equivalent to `-mtune`). + * `<feature>`/`no-<feature>` - enables/disables specific features. + +- Only report the first range error if there is actually more than one for + `__builtin_loongarch_cacop_[wd]`. + +- Add support for the `_Float16` type. And fix incorrect ABI lowering of `_Float16` + in the case of structs containing fp16 that are eligible for passing via `GPR+FPR` + or `FPR+FPR`. Also fix `int16` -> `__fp16` conversion code gen, which uses generic LLVM + IR rather than `llvm.convert.to.fp16` intrinsics. + +- Add support for the `__bf16` type. + +- Fix `-mno-lsx` option not disabling LASX feature. When `-march` with LASX feature and + `-mno-lsx` options are used together, `-mno-lsx` fails to disable LASX, leaving + `HasFeatureLASX=true` and causing incorrect `__loongarch_sx/asx=1` macro definition. + +- Fix incorrect _BitInt(N>64) alignment. Now consistently uses 16-byte alignment for all + `_BitInt(N)` where N > 64. + RISC-V Support ^^^^^^^^^^^^^^ _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
