The file lists supported platforms and tools, and it gives suggestions how to use configure options depending on platform and toolchain. Previously, these instructions were available at: https://bugs.kde.org/show_bug.cgi?id=270777. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@12676

Supported platforms
|
|
-------------------
|
|
- MIPS32 and MIPS32r2 platforms are currently supported.
|
|
- Both little-endian and big-endian cores are supported.
|
|
|
|
|
|
Building V for MIPS
|
|
-------------------
|
|
- Native build is available for all supported platforms. The build system
|
|
expects that native GCC is configured correctly and optimized for the platform.
|
|
Yet, this may not be the case with some Debian distributions which configure
|
|
GCC to compile to "mips1" by default. Depending on a target platform, using
|
|
CFLAGS="-mips32r2" or CFLAGS="-mips32" will do the trick and compile Valgrind
|
|
correctly.
|
|
- Use of cross-toolchain is supported as well.
|
|
- Example of configure line and additional configure options:
|
|
|
|
$ ./configure --host=mipsel-linux-gnu --prefix=<path_to_install_directory>
|
|
[--with-pagesize=<4|16|64>]
|
|
|
|
* --host=mips-linux-gnu is necessary only if Valgrind is built on platform
|
|
other then MIPS, tools for building MIPS application have to be in PATH.
|
|
|
|
* --with-pagesize option is used to set default PAGE SIZE. If option is not
|
|
used, PAGE SIZE is set to value default for platform on which Valgrind is
|
|
built on. Possible values are 4, 16 of 64 and represent size in kilobytes.
|
|
|
|
* --host=mips-linux-gnu is necessary if you compile it with cross toolchain
|
|
compiler for big endian platform.
|
|
|
|
* --host=mipsel-linux-gnu is necessary if you compile it with cross toolchain
|
|
compiler for little endian platform.
|
|
|
|
* --build=mips-linux is needed if you want to build it for MIPS32 on 64-bit
|
|
MIPS system.
|
|
|
|
* If you are compiling Valgrind with gcc version older then gcc (GCC) 4.5.1
|
|
you must specify CFLAGS="-mips32r2 -mplt", e.g.
|
|
./configure --prefix=<path_to_install_directory>
|
|
CFLAGS="-mips32r2 -mplt"
|
|
|
|
|
|
Limitations
|
|
-----------
|
|
- Currently, memcheck, massif, lackey, callgrind and none are supported.
|
|
- Support for helgrind, drd and exp-ptrcheck is still incomplete.
|
|
- Some Valgrind tests for MIPS expect mips32r2 architecture and will not
|
|
compile when target is one of the older instruction sets.
|
|
- Older GCC may have issues with some inline assembly blocks. Get a toolchain
|
|
based on newer GCC versions, if possible.
