With gcc ported to SCO Unix, I am interested in using the -a
option of gcc. This option generates extra code to write profile
information for basic blocks to a file (prog.d) The tool tcov uses
this file.
When I try to use gcc -a as we currently have gcc built, I get
the message:
gcc-cc1: warning: `-a' option (basic block profile) not supported
The code generating this message is in toplev.c:
#if !defined (BLOCK_PROFILER) || !defined (FUNCTION_BLOCK_PROFILER)
warning ("`-a' option (basic block profile) not supported");
#else
profile_block_flag = 1;
#endif
Has anyone successfully defined the flags BLOCK_PROFILER and/or
FUNCTION_BLOCK_PROFILER to get the -a option to work?
thanks,
Tammie Nelson
