A small clarification: the SIMPLE-ARM implementation can also be selected at runtime, e.g. with the '-idct simplearm' option. That's mainly useful for debugging purposes, though.
Regarding the binutils bug: Attached testcase test.S doesn't require compiling ffmpeg, but simply: $ gcc -g -c -o test.o test.S Analyzing the difference of 'objdump -d test.o' between variants built with working and broken binutils show that the working binutils always always uses 'ldr.w' for ldr, while the broken version sometimes optimizes this to 'movw', which is a correct alternative, but one time to 'movt', which only sets half of the register. ** Attachment added: "testcase" https://bugs.launchpad.net/ubuntu/+source/ffmpeg/+bug/1513985/+attachment/4516473/+files/test.S -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1513985 Title: ffmpeg test idct8x8 (SIMPLE-ARM) fails on ARM32 when built with binutils from the trunk To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/1513985/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
