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.
