Subject: testsuite: Port asm-hard-reg tests for PRU
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d020b73ce0002926866f506898cacfe54417e148;p=thirdparty%2Fgcc.git

testsuite: Port asm-hard-reg tests for PRU

Add the necessary register definitions for PRU, so that asm-hard-reg
tests can pass for PRU.

gcc/testsuite/ChangeLog:

	* gcc.dg/asm-hard-reg-error-1.c: Enable test for PRU, and define
	registers for PRU.
	* gcc.dg/asm-hard-reg-error-4.c: Define hard regs for PRU.
	* gcc.dg/asm-hard-reg-error-5.c: Ditto.
