- Subject: help in deciphering a call RTL instruction
I have a need to understand some call RTL instructions,
but I have difficulties to understand some of them.
Here are two examples of the challenging RTL instructions:
(call (mem:QI (symbol_ref:SI (\"stpcpy\") [flags 0x41] <function_decl 0x401f000
0 __builtin_stpcpy>) [0 S1 A8])
(const_int 8 [0x8]))
Q: does this instruction call the function stpcpy or __builtin_stpcpy ?
(call (mem:QI (symbol_ref:SI (\"check_match.7758\") [flags 0x3] <function_decl
0x404a3e80 check_match>) [0 S1 A8])
(const_int 0 [0x0]))
Q: does this instruction call the function check_match.7758 or check_match ?
In general, why do we have somtimes calls like that which (seemingly) have
different callee targets ?
