DescDetail: <<
It works as follows:
gcc compilation is divided into 3 steps:
1) cpp : the sources files a preprocessed into one C/C++ file (send
though a pipe, or written into a temporary file)
2) cc1/cc1plus : the preprocessed file is concerted into an assembly
language file
3) as : the assembly language file is converted into an object file
cachecc1 assumes that if
1) the input of cc1/cc1plus is the same
2) cc1/cc1plus is the same
3) the cc1/cc1plus invocation parameters are the same
then the output is the same.
cachecc1.so does the following :
1) overload exec* calls of the libc library in order to :
2) disable the '-pipe' parameter sometimes given to gcc (cachecc1
breaks the parallelism that allows '-pipe', and reading results
from cpp and cc1/cc1plus in files is a lot faster that reading
pipes, so '-pipe' does not make sense in this context)
3) wrap calls to cc1/cc1plus/as
<<
DescUsage: <<
To use it, you need to define 2 variables:
1) CACHECC1_DIR : the pathname of the cache
2) LD_PRELOAD : to tell the dynamic loader to load cachecc1.so
<<
DescPackaging: <<
The cachecc1.so plug-in is installed in %p/lib/.
<<
DescPort: <<
This was never ported to darwin before, and could use some help,
especially regarding .global assembly directives.
