This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H. Johnson <robbat2@gentoo.org> X-Thanks: Alec Warner <antarus@gentoo.org> - did the GSoC 2006 migration tests X-Thanks: Robin H. Johnson <robbat2@gentoo.org> - infra guy, herding this project X-Thanks: Nguyen Thai Ngoc Duy <pclouds@gentoo.org> - Former Gentoo developer, wrote Git features for the migration X-Thanks: Brian Harring <ferringb@gentoo.org> - wrote much python to improve cvs2svn X-Thanks: Rich Freeman <rich0@gentoo.org> - validation scripts X-Thanks: Patrick Lauer <patrick@gentoo.org> - Gentoo dev, running new 2014 work in migration X-Thanks: Michał Górny <mgorny@gentoo.org> - scripts, QA, nagging X-Thanks: All of other Gentoo developers - many ideas and lots of paint on the bikeshed

# @BLURB: Common functions for cuda packages
|
|
# @DESCRIPTION:
|
|
# This eclass contains functions to be used with cuda package. Currently it is
|
|
# setting and/or sanitizing NVCCFLAGS, the compiler flags for nvcc. This is
|
|
# automatically done and exported in src_prepare() or manually by calling
|
|
# cuda_sanatize.
|
|
# @EXAMPLE:
|
|
# inherit cuda
|
|
|
|
# @ECLASS-VARIABLE: NVCCFLAGS
|
|
# @DESCRIPTION:
|
|
# nvcc compiler flags (see nvcc --help), which should be used like
|
|
# CFLAGS for c compiler
|
|
: ${NVCCFLAGS:=-O2}
|
|
|
|
# @ECLASS-VARIABLE: CUDA_VERBOSE
|
|
# @DESCRIPTION:
|
|
# Being verbose during compilation to see underlying commands
|
|
: ${CUDA_VERBOSE:=true}
|
|
|
|
# @FUNCTION: cuda_gccdir

|
|
# @DESCRIPTION:
|
|
# Helper for determination of the latest gcc bindir supported by
|
|
# then current nvidia cuda toolkit.
|

# Example:
|
|
# @CODE
|
|
# cuda_gccdir -f
|
|
# -> --compiler-bindir="/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.3"
