Subject: sim/erc32: Add ATTRIBUTE_PRINTF
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=682389d557f7fa472b66de568ab0089d754ed757;p=binutils-gdb.git

sim/erc32: Add ATTRIBUTE_PRINTF

Clang generates a warning if the format string of a printf-like function is
not a literal ("-Wformat-nonliteral").  On the default configuration, it
causes a build failure (unless "--disable-werror" is specified).

To avoid warnings on the printf-like wrapper, it requires proper
__attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason.

This commit adds ATTRIBUTE_PRINTF to the printf-like functions.
