Running v8 test v7 with jsc in debug mode on our ARMv7 board I received this ASSERT failure:
Starting program: /data/kilvadyb/webkit-arm/webkit/WebKitBuild/Debug/bin/jsc run.js
[Thread debugging using libthread_db enabled]
[New Thread 0x42dc4400 (LWP 1111)]

ASSERTION FAILED: canBeJumpT4(instruction, target)
/data/kilvadyb/webkit-arm/webkit/Source/JavaScriptCore/assembler/ARMv7Assembler.h(2475) : static void JSC::ARMv7Assembler::linkJumpT4(uint16_t*, void*)
Program received signal SIGSEGV, Segmentation fault.

2475 ASSERT(canBeJumpT4(instruction, target));
(gdb)
I had similar problem on MIPS where a replaceWithJump would be easier to implement with direct jump instead of jump via register.
