No, because -m32 is a Linux-specific flag. And Valgrind for Mac OS X by default supports both 32 and 64 bit binaries. > What is the remedy? I don't know. It works fine here on Mac OS X 10.6 with Valgrind 3.8.0: $ fpc -gv prog.pp Free Pascal Compiler version 2.6.0 [2011/12/30] for i386 Copyright (c) 1993-2011 by Florian Klaempfl and others Target OS: Darwin for i386 Compiling prog.pp Compiling unit1.pp Assembling (pipe) unit1.s Assembling (pipe) prog.s Linking prog 18 lines compiled, 1.2 sec $ valgrind --tool=cachegrind ./prog ==790== Cachegrind, a cache and branch-prediction profiler ==790== Copyright (C) 2002-2011, and GNU GPL'd, by Nicholas Nethercote et al. ==790== Using Valgrind-3.8.0.SVN and LibVEX; rerun with -h for copyright info ==790== Command: ./prog ==790== --790-- ./prog: --790-- dSYM directory is missing; consider using --dsymutil=yes ==790== ==790== I refs: 1,061,926 ==790== I1 misses: 1,811 ==790== LLi misses: 1,372 ==790== I1 miss rate: 0.17% ==790== LLi miss rate: 0.12% ==790== ==790== D refs: 541,094 (384,427 rd + 156,667 wr) ==790== D1 misses: 2,997 ( 1,802 rd + 1,195 wr) ==790== LLd misses: 2,156 ( 1,326 rd + 830 wr) ==790== D1 miss rate: 0.5% ( 0.4% + 0.7% ) ==790== LLd miss rate: 0.3% ( 0.3% + 0.5% ) ==790== ==790== LL refs: 4,808 ( 3,613 rd + 1,195 wr) ==790== LL misses: 3,528 ( 2,698 rd + 830 wr) ==790== LL miss rate: 0.2% ( 0.1% + 0.5% You may want to look at the Instruments application that comes with Xcode though. That one offers a lot of different profiling options based on performance counters and sampling.
