Hello everyone,
I’m trying to building webkit with JIT enabled in my Android 2.2 project but I get errors like this:
/tmp/ccrx2gC4.s: Assembler messages:
/tmp/ccrx2gC4.s:24: Error: selected processor does not support `stmdb sp!,{r1-r3}'
/tmp/ccrx2gC4.s:25: Error: selected processor does not support `stmdb sp!,{r4-r8,lr}'

/tmp/ccrx2gC4.s:67: Error: lo register required -- `ldr lr,[sp,#64]'
/tmp/ccrx2gC4.s:72: Error: lo register required -- `str lr,[sp,#64]'
…
I believe this is because I’m using a Thumb compiler, so I modified Source/JavaScriptCore/Android.mk to something like this:
- Jit/xxx.cpp
+ jit/xxx.cpp.arm
So JIT code is compiled by ARM compiler, build was successed and ran quite smoothly on my phone. But after a while frequently
refreshing www.apple.com<http://www.apple.com/>, which is contained lots of js file, Webkit crashed mysterious without stack backtrace, so I even don’t
know where to start my investigation.

Can anyone point a direction for me or I should continue to digging it myself?
Thanks
