Subject: compiler: Report errors for malformed builtin calls.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1393eb7608ccdfd5a8a5c234823eab49117427f6;p=gcc.git

compiler: Report errors for malformed builtin calls.


    Errors reported from malformed builtin calls are handled in a later
    pass than the one in which they are detected.  If a malformed builtin
    call is lowered into an error expression too early, these errors will
    never be reported.

    Fixes golang/go#11561.
