From: Simon Marchi Date: Thu, 30 Apr 2020 00:35:33 +0000 (-0400) Subject: gdb: fix shellcheck warnings SC2059 (variables in printf format string) in gdbarch.sh X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8d113d130ef87c982896412f89154a5fa5afc9ac;p=binutils-gdb.git gdb: fix shellcheck warnings SC2059 (variables in printf format string) in gdbarch.sh Fix all instances of this: In gdbarch.sh line 2182: printf " gdb_assert (!(${invalid_p}));\n" ^-- SC2059: Don't use variables in the printf format string. Use printf "..%s.." "$foo". ... by doing exactly as the message suggests. The rationale explained here [1] makes sense, if there happens to be a format specifier in text substituted for the variable, the printf won't do what we expect.
