Subject: Fix multi-statment macro
X-Git-Tag: basepoints/gcc-13~4835
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f42e95a830ab48e59389065ce79a013a519646f1;p=thirdparty%2Fgcc.git

Fix multi-statment macro

INIT_CUMULATIVE_ARGS() expands to multiple statements, which will break right
after an `if` statement. Wrap it into a block.

gcc/ChangeLog:

	* config/alpha/vms.h (INIT_CUMULATIVE_ARGS): Wrap multi-statment
	define into a block.
