Hi,
In order to be able to respond quicker to compiler changes/bugs/tests, I
decided to configure my own toolchain
(http://people.debian.org/~debacle/cross.html).
Even though, with some trial and error, I got everything working, but I
have one strange effect: compared with our current commercial
distribution (MVL 3.1), the binaries that are compiled with the "debian"
compiler take an immediate performance hit of at least 10%.
Any suggestions or comments on this?
btw, are there any sites out there which have source packages for
powerpc: (or clean and up-to-date HOWTO) even though I have compiled
my fair share of debian packages; finding out and getting all the cross
compilations options to work seems to be not that obvious.
