Here is a diff of the assembly output from gcc 2.7.0 Vs. 2.7.2 diff test.s.gcc2.7.0 test.s.gcc2.7.2 2c2,3 < .stabs "/h/USERS/adesai/c_programs/c++",100,0,0,.LLtext0 --- > .stabs "gcc2_compiled.", 0x3c, 0, 0, 0 > .stabs "/h/USERS/adesai/c_programs/c++/",100,0,0,.LLtext0 6d6 < .stabs "gcc2_compiled.", 0x3c, 0, 0, 0 48,49d47 < b .LL1 < nop 54,55d51 < b .LL1 < nop 69c65 < .ident "GCC: (GNU) 2.7.0" --- > .ident "GCC: (GNU) 2.7.2" The line .stabs "gcc2_compiled.", 0x3c, 0, 0, 0 is now the 2nd line instead of after .section ".text" in 2.7.0 , this causes purify to barf i.e. mercator(235)% purify gcc test.gcc2.7.0.s Purify 3.0 Solaris 2, Copyright 1992-1994 Pure Software Inc. Instrumenting: cca004hU1.o Linking fine but mercator(236)% purify gcc test.gcc2.7.2.s Purify 3.0 Solaris 2, Copyright 1992-1994 Pure Software Inc. Instrumenting: cca004hg1.o Purify engine: While processing file /var/tmp/cca004hg1.o: Warning: Debug contribution does not start with N_SO stabs. Debug information may not be correct. Linking I have sent a bug report to purify but I was not sure if the movement of that line was ok or not?? ======================================================================== | Ajay M.
