Ticket #322 (Fixed)Thu Oct 18 12:26:47 UTC 2012

objasm 4.01 incorrectly assembles some VMOV instructions

Reported by: Jeffrey Lee (213) Severity: Normal
Part: RISC OS: C/C++ toolchain Release:
Milestone: Status Fixed

Details by Jeffrey Lee (213):

Copied from the bugs forum now that the bug tracker is back up:

The ARM -> VFP/NEON version of the doubleword VMOV instruction (section A8.6.332 in the ARMv7 ARM) is being assembled incorrectly. It looks like the Rt field is being corrupted; e.g. “VMOV d26,r3,r4” assembles to 0xec44bb3a (VMOV d26,r11,r4), and “VMOV d27,r5,r6” assembles to 0xec46fb3b (VMOV d27,pc,r6).

The VFP/NEON -> ARM version of the instruction seems to work fine.

Changelog:
