Subject: testsuite/52641 - Make gcc.dg/strict-flex-array-3.c work on int != 32 bits.
X-Git-Tag: basepoints/gcc-16~5521
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=77c3ef08e946306329070ea6415abe7d9e328cd6;p=thirdparty%2Fgcc.git

testsuite/52641 - Make gcc.dg/strict-flex-array-3.c work on int != 32 bits.

	PR testsuite/52641
gcc/testsuite/
	* gcc.dg/strict-flex-array-3.c (expect) [AVR]: Use custom
	version due to AVR-LibC limitations.
	(stuff): Use __SIZEOF_INT__ instead of hard-coded values.
