6 Valgrind has 2 main levels of genericity.
8 1. Multiple tools, plus the core.
9 2. Multiple architectures, OSes, and platforms (arch/OS combinations).
11 This file is a guide to where different things live.
16 1. Core stuff lives in:
17 - include/ for declarations that must be seen by tools
18 - coregrind/ for code that need not be seen by tools
20 Some subdirs of coregrind/ hold modules that consist of multiple files.
24 - $TOOL/tests regression tests
25 - $TOOL/docs documentation
28 - docs/ main, non-tool-specific docs
29 - tests/ regression test machinery
30 - nightly/ overnight test stuff (should be in tests/)
31 - auxprogs/ auxiliary programs
33 2. Generic things go in the directory specified in (1).
35 Arch-specific, OS-specific, or platform-specific things are sprinkled
36 throughout the code -- there is no single place for all the
37 architecture-specific things, for example.
39 Sometimes we have a whole file holding things specific to a particular
40 arch/OS/platform. Such files have an appropriate suffix, eg.
43 More often we use #ifdefs inside source files to specify the different
44 cases for different archs/OSes/platforms. It's pretty straightforward.
46 A final case: arch-specific regression tests for tools go in a
47 subdirectory, eg. cachegrind/tests/x86/.
52 See coregrind/README_MODULES.txt for details of the core/tool header file
55 Note that every single C file will #include pub_basics.h. Every single asm
56 file will #include pub_basics_asm.h.
58 Our versions of kernel types are in the vki*.h headers.
60 When searching for something, rgrep is very useful. If you don't have a
61 version of rgrep, use a command something like this:
63 find . -name '*.h' | xargs grep <pattern>
67 -not -path '*.svn\/*' | xargs grep "$1"
69 The -name option gives the file wildcard, the -type says "look in normal
70 files only" and the -not -path tells it to not look in Subversions hidden
