Subject: [builtins] Add __cmpsf2 for ARM version of comparesf2
X-Git-Tag: llvmorg-10-init~7660
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=64c32362f053b198f1ad49ca6253b03ee0f056d5;p=platform%2Fupstream%2Fllvm.git

[builtins] Add __cmpsf2 for ARM version of comparesf2

The generic version of comparesf2 defines __cmpsf2 alias for libgcc
compatibility, but the ARM overlay is missing the alias.
