Is there a # or other directive in gcc that signals gprof to sum and report the times for a block of lines within a function? That is, put something like this in the source code: #define gprof_block block1 /* many many lines of C code */ #undef gprof_block #define gprof_block block2 /* many many lines of C code */ #undef gprof_block compile with -pg, run gprof, and then output of gprof would then have entries for block1 and block2, showing how much time was spent in each block of lines? When there are a couple of hundred lines per block it can be difficult to figure out how much total time is spent in logical block 1 vs. logical block 2, since the only method provided seems to be to add up the times for all the lines in each block. Doing that seems a sure way to end up with unreliable numbers due to rounding and truncation errors.
