From 4d23ca4b5fe6b9409b2738764c916564710dcc54 Mon Sep 17 00:00:00 2001 From: Fabjan Sukalia Date: Fri, 10 Mar 2017 23:32:31 +0100 Subject: [PATCH] rustc: Whitelist the FMA target feature This commit adds the entry `"fma\0"` to the whitelist for the x86 target. LLVM already supports fma but rustc did not directly. Previously rustc permitted `+fma` in the target-feature argument and enabled the use of FMA instructions, but it did not list it in the configuration and attributes. fixes #40406 --- src/librustc_driver/target_features.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/librustc_driver/target_features.rs b/src/librustc_driver/target_features.rs index 0744fbbd4e9..4f3abbb362f 100644 --- a/src/librustc_driver/target_features.rs +++ b/src/librustc_driver/target_features.rs @@ -25,7 +25,7 @@ const ARM_WHITELIST: &'static [&'static str] = &["neon\0", "vfp2\0", "vfp3\0", " const X86_WHITELIST: &'static [&'static str] = &["avx\0", "avx2\0", "bmi\0", "bmi2\0", "sse\0", "sse2\0", "sse3\0", "sse4.1\0", "sse4.2\0", "ssse3\0", "tbm\0", "lzcnt\0", "popcnt\0", - "sse4a\0", "rdrnd\0", "rdseed\0"]; + "sse4a\0", "rdrnd\0", "rdseed\0", "fma\0"]; /// Add `target_feature = "..."` cfgs for a variety of platform /// specific features (SSE, NEON etc.).
