NAME


builder-cc - gcc wrapper to facilitate pentium-optimizations

SYNOPSIS


export DEBIAN_BUILDARCH=architecture
export DEBIAN_BUILDGCCVER=gcc-version
gcc ...

DESCRIPTION


The builder-cc wrapper is normally used by calling gcc as usual. If the environment
variable DEBIAN_BUILDARCH is not set, builder-cc does nothing, and the real gcc is invoked
with the specified arguments.

When the DEBIAN_BUILDARCH environment variable is set, builder-cc invokes gcc with the
specified arguments, plus -mcpu=DEBIAN_BUILDARCH -march=DEBIAN_BUILDARCH This has the
effect of telling gcc to use architecture-specific optimizations without changing the
command line. This is particularly useful for package builds.

If DEBIAN_BUILDGCCVER is not set, builder-cc calls gcc.real. If DEBIAN_BUILDGCCVER is
set, builder-cc calls gcc-DEBIAN_BUILDGCCVER instead.

ENVIRONMENT


DEBIAN_BUILDARCH
If set, the architecture to compile for. Useful values are pentium or pentiumpro.

DEBIAN_BUILDGCCVER
If set, the version of gcc to be invoked. Useful values are 3.0 or 2.95.

NOTES


The real gcc is renamed gcc.real, and a diversion is registered with dpkg-divert(1). Thus
builder-cc's idea of the default gcc is dictated by whatever package installed
/usr/bin/gcc.
