In general, armhf platforms do not create frame chains using r7/r11. However, when using only thumb or arm mode, and compiling with frame pointers enabled, this does work. This patch adds very simple support for frame chain unwinding on armhf.

This is still a WIP, but I want to get this working for programs compiled with -mframe-chain=aapcs+leaf too. Today, JavaScriptCore uses r7 for the jit code FP, so I will also try to add an option to change that. |
