Hello,
Sorry for the last mail. It got all screwed by as my internet mailer was adding HTML
tags.
Coming back to the point, I was looking at the runtime invoke code generated for
Assembly.DoAssemblyLoad(). (which comes from mono_domain_fire_assembly_load). Now
while the code is being compiled using
mono_method_compile-->mono_codegen()-->mono_arch_local_regalloc() I found that the
follwing instructions were looked up in the **ppcg4 array.
372: load_membase
312: compare_imm
59 : beq
..
..
..
56 : br
551: start_handler
^^^^^^^^^^^^^
Now in the "cpu-g4.h" the value assigned to "start_handler" is "NULL" which makes the
code inside the mono_arch_local_regalloc ..
while(ins) {
spec = ins_spec[ins->opcode];
..
if (spec[MONO_INST_SRC1]) {
..
}
.. to crash as spec becomes NULL and the if block tried to access a NULL pointer.
After hacking the code to work around this exception, I later found the when the
emitted code is run through mono_ldftn() the MonoMethod *method is corrupted and it
crashes again.
Is there still some problem with the ppc emitter or I am missing something in here.
any pointers would be appreciated.
regards,
gary
