Hello,
Is the fact that the cache size limit is only configurable as a
commandline option intentional ? There seem to be environment
vars for virtually everything else but this.
I am asking because I am close to the 1GB limit and it would be
tedious to change some build scripts to use CC='ccache

I just did a quick search, and couldn't find discussions on the idea of
caching compiled objects as binary diffs from other existing objects.
Basically, before writing a new object file, ccache could find a similar
object in the cache (based on object-code or source-code hashes for
example) and st

Initial results from a small .ccache (3.0) dir:
- 6476 objects
- 300MB
- probably about 500-1000 compiles/recompiles of around 100 small to large
projects
The test was:
1. Find the candidates for compression, based on: objdump -t | grep " g "
(defined symbols). If two objects had at least 4 symbo

The previous results were bogus (I was diffing .gz compressed objects).
I tried the bsdiff approach on a new .ccache folder obtained from compiling
8 linux kernels (various v3.x ve
