Subject: [bootstrap-O3,fortran] add a NULL initializer to avoid a warning at -O3
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=692216906ba1c7734183c4940122d5684c05141f;p=gcc.git

[bootstrap-O3,fortran] add a NULL initializer to avoid a warning at -O3

Building with the bootstrap-O3 configuration option fails to compile
fortran/module.c due to an AFAICT false-positive warning about an
uninitialized use of a variable.

This patch adds a dummy initializer to silence it.

for  gcc/fortran/ChangeLog

	* module.c (load_omp_udrs): Initialize name.
