[webkit-help] Assembler Error: bad instruction, while compiling with ARM-JIT enabled

[Srinivas Rao M Hamse]

Hello all,

I am trying to compile WebKit-r51580 for ARM with JIT option enabled. My
cross compiler version is 3.4.6; While i compile the sources i get following
error. Has anyone tried compiling ARM jit on lower versions of compiler. Is
there any wiki post which has a sequence of steps to take care for building
webkit on older compiler? However this issue is not seen when i compile it
for PC(x86 platform).

I read in the earlier posts that, JIT support is not yet present of GTK
builds. Has anyone made a complete ARM-JIT build for GTK ?
