Subject: testsuite: Fix up pr106070.c test [PR106070]
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=00063459f683adcd92ada8325984e6b10e9f7a95;p=platform%2Fupstream%2Fgcc.git

testsuite: Fix up pr106070.c test [PR106070]

The test FAILs on 32-bit targets, because when unsigned long
is 32-bit, (unsigned long) -1 isn't 0xffffffffffffffff.
The options to fix this would be either using -1UL, or switch
to unsigned long long and using -1ULL, I chose the latter because
the test then FAILs in r13-1242 even on 32-bit targets.
And while at it, some deobfuscation and formatting tweaks.

2022-06-27  Jakub Jelinek  <jakub@redhat.com>

	PR tree-optimization/106070
	* gcc.dg/torture/pr106070.c: Use unsigned long long instead of
	unsigned long and -1ULL instead of 0xffffffffffffffff, deobcuscate
	and improve formatting.
