Trevor Gross	851aa05aa0	cleanup: Reuse MinInt and Int from libm in compiler-builtins ... Since the two crates are now in the same repo, it is easier to share code. Begin some deduplication with the integer traits.	2025-05-29 03:04:59 +00:00
Trevor Gross	4c264c96ae	Update CmpResult to use a pointer-sized return type ... As seen at [1], LLVM uses `long long` on LLP64 (to get a 64-bit integer matching pointer size) and `long` on everything else, with exceptions for AArch64 and AVR. Our current logic always uses an `i32`. This happens to work because LLVM uses 32-bit instructions to check the output on x86-64, but the GCC checks the full 64-bit register so garbage in the upper half leads to incorrect results. Update our return type to be `isize`, with exceptions for AArch64 and AVR. Fixes: https://github.com/rust-lang/compiler-builtins/issues/919 [1]: 0cf3c437c1/compiler-rt/lib/builtins/fp_compare_impl.inc (L11-L27)	2025-05-28 02:58:42 -04:00
Trevor Gross	8d70be87e6	Run cargo fmt on all projects ... Apply the same formatting rules to both `libm` and `compiler-builtins`.	2025-04-19 19:05:49 -04:00
Trevor Gross	92b1e8454d	Rename testcrate to builtins-test ... The repo will soon have `libm` as a top-level crate, so make it clear that this is only the test crate for `compiler-builtins`.	2025-04-18 21:14:41 -04:00
