+++ This bug was initially created as a clone of Bug #103146 +++ 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)] Richards: 161 DeltaBlue: 21.8 Crypto: 110 RayTrace: 101 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. 0x4040b38c in JSC::ARMv7Assembler::linkJumpT4 (instruction=0x455695f6, target=0x43599dc0) at /data/kilvadyb/webkit-arm/webkit/Source/JavaScriptCore/assembler/ARMv7Assembler.h:2475 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.
