Subject: cmd/go: correct gccgo buildid file on ARM
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e47515aa894046a8ebab87395d291fbbb1ccbd61;p=gcc.git

cmd/go: correct gccgo buildid file on ARM

    Bring in https://golang.org/cl/135297 from the gc repository to fix a
    GCC bug report.

    Original CL description:

        The GNU assembler for ARM treats @ as a comment character, so section
        types must be written using % instead.

        Fixes https://gcc.gnu.org/PR87260.
