Subject: [X86] Correct result type for the flag result of RDSEED and RDRAND nodes. Correct... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ee0bb0a0d797bb4972bc6ed100c0bdb8238da924;p=llvm

[X86] Correct result type for the flag result of RDSEED and RDRAND nodes. Correct the CC type for the CMOV used with RDSEED/RDRAND.

The flag result was MVT::Glue, but should be MVT::i32. The CC type was MVT::i8, but should be MVT::i32.
