Subject: nvptx: Silence unused variable warning in output_constant_pool_contents()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d2253f407e73013cb6b7b045c120d4acf35bdc5;p=thirdparty%2Fgcc.git

nvptx: Silence unused variable warning in output_constant_pool_contents()

Similar to the rs6000 code, nvptx defines ASM_OUTPUT_DEF_FROM_DECLS as well as
ASM_OUTPUT_DEF. Make sure that the define's parameters are used by referencing
them as (void) to silence a warning in output_constant_pool_contents().

	* config/nvptx/nvptx.h (ASM_OUTPUT_DEF): Reference macro arguments.

(cherry picked from commit 08de065293f8b08158e1089fbacce9dbaba95077)
