Subject: C main 32/64 bit prologues differ
Date: Fri, 22 Feb 2008 20:39:00 -0000 [thread overview]
Message-ID: <1203710407.6360.20.camel@localhost> (raw)
The prologues for the main function in C differ (at the assembly
language level) depending on whether it is compiled for 32-bit or 64-bit
in the x86 architecture.
Also, adding a dwarf2 unwind table is the default in 64-bit mode, but
not in 32-bit.
Can anyone point me to discussions about why it's done this way?
