Dump the current code stream when the assembler fails on size issues.
Since the assembler is very robust and will recover from such problems,
adding the verbose/noisy mode will make it easier to detect overly
aggressive optimizations that don't actually work.
Example:
D/dalvikvm( 2348): Assembler abort #1 on 1
D/dalvikvm( 2348): kThumbBCond@16: delta=260
:
Instruction at 0x16 is a conditional branch:
D/dalvikvm( 2348): 0x16 (0016): beq 0x0000001a (L0xb6c0c)
:
Label at L0xb6c0c is a PC reconstruction cell:
D/dalvikvm( 2348): L0xb6c0c:
D/dalvikvm( 2348): -------- reconstruct dalvik PC : 0x401854d6 @ +0x002b
D/dalvikvm( 2348): 0x11e (011e): ldr r0, [r15pc, #0]
D/dalvikvm( 2348): 0x122 (0122): b 0x00000126 (L0xb685c)
where 0x11e - 0x16 - 4 = 260
