Hi, Need workaround/remedy to disable GCC noreturn type optimization for abort to get useful coredump in abort () crash I have build libc 2.5 with "-fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-builtin-abort -fno-crossjumping -O2 " using gcc 4.2.1. But still core genrated on abort call is useless. I went through thread http://sourceware.org/bugzilla/show_bug.cgi?id=3D6522but could get much out of it. when i disassembled libc with objdump, I can see fp is NOT stored 0002ba10 <atoll>: 2ba10: e92d4800 push {fp, lr} 2ba14: e3a01000 mov r1, #0 ; 0x0 2ba18: e28db004 add fp, sp, #4 ; 0x4 2ba1c: e3a0200a mov r2, #10 ; 0xa 2ba20: e1a03001 mov r3, r1 2ba24: eb000c4b bl 2eb58 <__strtoll_internal> 2ba28: e8bd8800 pop {fp, pc} 0002ba2c <abort>: 2ba2c: e59f8390 ldr r8, [pc, #912] ; 2bdc4 <abort+0x398> 2ba30: e59fa390 ldr sl, [pc, #912] ; 2bdc8 <abort+0x39c> 2ba34: e24db004 sub fp, sp, #4 ; 0x4 2ba38: e08f8008 add r8, pc, r8 2ba3c: e24dde11 sub sp, sp, #272 ; 0x110 2ba40: e088300a add r3, r8, sl 2ba44: e5932008 ldr r2, [r3, #8] 2ba48: ebffa4a8 bl 14cf0 <__aeabi_read_tp> Am I missing something?
