Assembly programming in Mint

[turboscrew]

Didn't come up with any better place to ask this, but:
Does anyone have an idea how Mint handles the command line parameters?

I wrote a small toy program, in AT&T form assembly, and if I compile it with GCC it works fine, but
if I compile it with GAS, the command line parameters are garbage, and the program dies in segmentation fault.

Any pointers to where can I find the righ way to do the command line parameter handling so, that it'd work with GAS too.

Ah, GCC adds a prologue that rearanges the parameters and calls "main".

Code: Select all

# GCC
# Stack is:
#ESP -> ret addr
#		argc
#		argv -> argv[0] -> "program name"
#				argv[1] -> "Key"
#				argv[2] -> "Infile"
#				argv[3] -> "Outfile"

# GAS
# Stack is:
#ESP -> argc
#		argv[0] -> "program name"
#		argv[1] -> "Key"
#		argv[2] -> "Infile"

# argv[3] -> "Outfile"
