Janne Grunau	7b1ae0e73a	checkasm/arm: preserve the stack alignment checkasm_checked_call ... The stack used by checkasm_checked_call_vfp was a multiple of 4 when the checked function is called. AAPCS requires a double word (8 byte) aligned stack public interfaces. Since both calls are public interfaces the stack is misaligned when the checked is called. Might fix the SIGBUS error in the armv7-linux-clang-3.7 fate config.	2016-07-13 22:18:53 +02:00
Janne Grunau	8c816c0c9b	checkasm/arm: align the clobber check data properly for ldrd ... Should fix the SIGBUS in the armv7-linux-clang-3.7 fate target.	2016-07-10 13:35:41 +02:00
Martin Storsjö	26ec75aec3	checkasm: Check register clobbering on arm ... Use two separate functions, depending on whether VFP/NEON is available. This is set to require armv5te - it uses blx, which is only available since armv5t, but we don't have a separate configure item for that. (It also uses ldrd, which requires armv5te, but this could be avoided if necessary.) Signed-off-by: Martin Storsjö <martin@martin.st>	2016-01-07 09:33:24 +02:00
