Subject: fix build failure for sh4a due to missing colon in asm statement
X-Git-Tag: v1.1.17~31
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1698fe6cdcdeaad03aa19a85433d5396ecfc51ef;p=oweals%2Fmusl.git

fix build failure for sh4a due to missing colon in asm statement

Due to a missing ":" in an asm() statement, the "memory" clobber is
considered by gcc as an input operand and not a clobber, which causes a
build failure.
