Subject: stabs and macro information
Date: Wed, 16 Apr 2003 15:58:00 -0000 [thread overview]
Message-ID: <200304161558.h3GFwJV09359@mailhub.lss.emc.com> (raw)
Currently, when invoked with -gdwarf-2 -g3, gcc will record macro
information in a .debug_macinfo elf section. And when presented with
an executable containing macro information in a .debug_macinfo
section, gdb will make use of it.
Many companies, including EMC, still use stabs. So... it would be
nice if the same was true of stabs.
To that end, I have started to implement this.
The GCC side of things took less than a day to implement; I'm hoping
to get started on the GDB side soon.
One question I have is what stabs types to use -- tentatively I'm using:
/* GNU extension. Macro define. */
__define_stab(N_MAC_DEFINE, 0x36, "MAC_DEFINE")
/* GNU extension. Macro undefine. */
__define_stab(N_MAC_UNDEF, 0x3a, "MAC_UNDEF")
as it appears (based on gcc/stab.def, include/aout/stab.def, and
gdb/doc/stabs.texinfo) that 0x36 and 0x3a are available.
Is anyone aware of any other uses of stab types 0x36 and 0x3a --
i.e. is anyone aware of uses that might conflict?
Thanks.
David
p.s. shouldn't include/aout/stab.def and gcc/stab.def be merged?
