hello all,
Sorry i am asking this kind of question.This might be weird to most of you but i am new to GCC.
Can somebody tell me how to analyze the below instruction pattern
(insn 8 6 9 1 (parallel [
(set (reg/f:SI 32)
(symbol_ref:SI ("t") <var_decl 0x402270b0 t>))
(clobber (reg:CC 21 cc))
]) -1 (nil)
(nil))
Will i be able to find this pattern in .md files?
what does insn 8 6 9 1 mean?
reg/f ?
for varible declaration why is it needed to clobber CC?
Hope somebody will help me.
Thanks in advance.
Regards,
Shafi
