Subject: fix x86_64 lrintl asm, again
X-Git-Tag: v0.9.14~18
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=2f1de8051b4b33445ca233868e573ec838c81f65;p=oweals%2Fmusl.git

fix x86_64 lrintl asm, again

the underlying problem was not incorrect sign extension (fixed in the
previous commit to this file by nsz) but that code that treats "long"
as 32-bit was copied blindly from i386 to x86_64.

now lrintl is identical to llrintl on x86_64, as it should be.
