Hello, gas(GNU as) developers.
I only talk about i386.
When gas deal with this assembly code:
---------------------------
call function_name
---------------------------
In static NO PIC, the relocation type of function_name in call
instruction must be R_386_PC32?
Is it possible R_386_32 in gas(GNU as)?
thx.

Well reading the gas source code I have found the answer.
binutils-source/gas/config/tc-i386.c
output_insn()
output_jump()
reloc()
When call the reloc() pass the 2ed argument :1, means it is PC-relative
