Subject: MIPS/GCC/testsuite: Fix data-sym-pool.c for n64 code
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b4d62b40b7741b009730d074f9b3991344895fc2;p=gcc.git

MIPS/GCC/testsuite: Fix data-sym-pool.c for n64 code

With the soft-float n64 ABI and the data-sym-pool.c test case code like
below is produced:

	.file	1 "data-sym-pool.c"
	.section .mdebug.abi64
	.previous
	.nan	legacy
	.module	softfloat
	.module	oddspreg
	.abicalls
	.option	pic0
	.text
	.align	2
	.globl	frob
	.set	mips16
	.set	nomicromips
	.ent	frob
	.type	frob, @function
frob:
	.frame	$17,16,$31		# vars= 0, regs= 1/0, args= 0, gp= 0
	.mask	0x00020000,-8
	.fmask	0x00000000,0
	daddiu	$sp,-16
	sd	$17,8($sp)
	move	$17,$sp
	ld	$2,.L3
	move	$sp,$17
	ld	$17,8($sp)
	daddiu	$sp,16
	jr	$31
	.type	__pool_frob_3, @object
__pool_frob_3:
	.align	3
.L3:
	.dword	305419896
	.type	__pend_frob_3, @function
__pend_frob_3:
	.insn
	.end	frob
	.size	frob, .-frob
	.ident	"GCC: (GNU) 8.0.1 20180410 (experimental)"

(we have no support for hard-float n64 MIPS16 code generation), which
means that the test case will fail, as the regular expression pattern
expects `lw' and `.word' rather than `ld' and `.dword' respectively to
appear in assembly code generation.  Correct the pattern in an obvious
way then making it accept both intructions and pseudo-ops.

	gcc/testsuite/
	* gcc.target/mips/data-sym-pool.c (dg-options): Match `ld' and
	`.dword' in addition to `lw' and `.word'.
