Is 64-bit version of Valgrind able to dig the memory issue of 32-bit program?

I have 64bit OS and Valgrind installed. And I need to check the memory problem of 32bit program right now. Valgrind can run and produce a report. But I wonder whether the report generated by Valgrind is able to deliver the correct information?

Solution

  • From Valgrind Documentation,

    Preliminary support for MacOSX 10.7 and XCode 4.Both 32- and 64-bit processes are supported

    There is experimental support for AIX 5.3, both 32-bit and 64-bit processes.

    Also,

    - New configuration flags:

     --enable-only32bit
 --enable-only64bit

    By default, on 64 bit platforms (ppc64-linux, amd64-linux) the build system will attempt to build a Valgrind which supports both 32-bit and 64-bit executables. This may not be what you want, and you can override the default behaviour using these flags.
