As reported by Christophe Lyon, gcc.target/arm/movdi_movw test fails on big
endian targets. This is because on big endian targets the low bits of a 64bit
value would be in the highest numbered register of a pair rather than the lowest
numbered register as on little endian targets. This patch fixes that by allowing
both r0 and r1. It also changes effective target to use arm_thumb2_ok instead of
arm_thumb2 to allow the test on ARM mode targets.
ChangeLog entry is as follows:
*** gcc/testsuite/ChangeLog ***
2016-10-11 Thomas Preud'homme <thomas.preudho...@arm.com>
* gcc.target/arm/movhi_movw.c: Enable test for ARM mode.
* gcc.target/arm/movsi_movw.c: Likewise.
* gcc.target/arm/movdi_movw.c: Likewise and adapt scan-assembler
directive to work on big endian targets.
Tested testcases with armeb-none-eabi for -march=armv8-a.
Is this ok for trunk?
