This patch builds and passes run-javascriptcore-tests --debug --32-bit --cloop --no-jsc-stress. This is the minimum patch that will build and run the 32-bit C loop LLINT. Since the C loop is based on ARM, this patch also fixes part of the ARMv7 LLINT implementation. There is still more to do for ARM (e.g. alignment issues) but I didn’t want to overlap with the work in Michael’s patch. There is still necessarily some minimal overlap with Michael’s patch. I’ll rebase this patch after Michael’s 32-bit patch is finalized. 968773 2 221343 oliver 2014-01-16 08:50:30 -0800 Comment on attachment 221343 the patch.

No, the sp adjustment (before and after the call) is needed for all 32-bit ports, and Michael’s patch will make that change. I have to make the same change here or the C loop code won’t work. 968787 4 221343 ggaren 2014-01-16 09:25:16 -0800 Comment on attachment 221343 the patch. r=me 969409 5 mark.lam 2014-01-17 23:23:27
