Hello, Working on GCC 4 based GNAT port for AIX 5.[23], our testsuite to evaluate GDB (6.4) debugging capabilities currently yields very unpleasant results compared to what we obtain with a GCC 3.4 based compiler (80+ extra failures out of 1800+ tests).
We so far presumed that this is caused by limitations in the XCOFF/STABS debug info format more heavily exposed by the many great compiler improvements between 3.4 and 4.x. I'd appreciate feedback on general questions from these observations: Is it generally known/expected that xcoff/stabs debugging capabilities degrade when moving from 3.4 to 4.x ? If yes, how is that considered by AIX GCC developers ? (how serious the issue, is it fixable, are there plans/attempts to move to DWARF2, ...) Thanks much in advance, With Kind Regards, Olivier
