| Series | [i386] : Fix PR93254, -msse generates sse2 instructions | expand |
Also, we can remove existing SSE2 ISA requirements for alternatives 14 and 15.
Remove invalid SSE2 ISA requirements in *movsf_internal.
2020-01-15 Uroš Bizjak <ubizjak@gmail.com>
* config/i386/i386.md (*movsf_internal): Do not require
SSE2 ISA for alternatives 14 and 15.
Patch was bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Committed to mainline, will be backported to gcc-9 branch.
Uros.
