Supported platforms<br>
|
||
-------------------<br>
|
||
- MIPS32 and MIPS64 platforms are currently supported.<br>
|
||
- Both little-endian and big-endian cores are supported.<br>
|
||
- MIPS DSP ASE on MIPS32 platforms is supported.<br>
|
||
<br>
|
||
<br>
|
||
Building V for MIPS<br>
|
||
-------------------<br>
|
||
- Native build is available for all supported platforms. The build system<br>
|
||
expects that native GCC is configured correctly and optimized for the platform.<br>
|
||
Yet, this may not be the case with some Debian distributions which configure<br>
|
||
GCC to compile to "mips1" by default. Depending on a target platform, using<br>
|
||
CFLAGS="-mips32r2", CFLAGS="-mips32" or CFLAGS="-mips64" or<br>
|
||
CFLAGS="-mips64 -mabi=64" will do the trick and compile Valgrind correctly.<br>
|
||
<br>
|
||
- Use of cross-toolchain is supported as well.<br>
|
||
- Example of configure line and additional configure options:<br>
|
||
<br>
|
||
$ ./configure --host=mipsel-linux-gnu --prefix=<path_to_install_directory><br>
|
||
[--with-pagesize=<4|16|64>]<br>
|
||
<br>
|
||
* --host=mips-linux-gnu is necessary only if Valgrind is built on platform<br>
|
||
other then MIPS, tools for building MIPS application have to be in PATH.<br>
|
||
<br>
|
||
* --with-pagesize option is used to set default PAGE SIZE. If option is not<br>
|
||
used, PAGE SIZE is set to value default for platform on which Valgrind is<br>
|
||
built on. Possible values are 4, 16 of 64 and represent size in kilobytes.<br>
|
||
<br>
|
||
* --host=mips-linux-gnu is necessary if you compile it with cross toolchain<br>
|
||
compiler for big endian platform.<br>
|
||
<br>
|
||
* --host=mipsel-linux-gnu is necessary if you compile it with cross toolchain<br>
|
||
compiler for little endian platform.<br>
|
||
<br>
|
||
* --build=mips-linux is needed if you want to build it for MIPS32 on 64-bit<br>
|
||
MIPS system.<br>
|
||
<br>
|
||
* If you are compiling Valgrind for mips32 with gcc version older then<br>
|
||
gcc (GCC) 4.5.1, you must specify CFLAGS="-mips32r2 -mplt", e.g.<br>
|
||
<br>
|
||
./configure --prefix=<path_to_install_directory><br>
|
||
CFLAGS="-mips32r2 -mplt"<br>
|
||
<br>
|
||
<br>
|
||
Limitations<br>
|
||
-----------<br>
|
||
- Some gdb tests will fail when gdb (GDB) older than 7.5 is used and gdb is<br>
|
||
not compiled with '--with-expat=yes'.<br>
|
||
- You can not compile tests for DSP ASE if you are using gcc (GCC) older<br>
|
||
then 4.6.1 due to a bug in the toolchain.<br>
|
||
- Older GCC may have issues with some inline assembly blocks. Get a toolchain<br>
|
||
based on newer GCC versions, if possible.<br>
