[DragonFlyBSD - Bug #2878] [fix] CCVER problem when using clang and cpu extensions (intrinsics)

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2878 has been updated by arcade at b1t.name.

Subject changed from CCVER problem when using clang and cpu extensions (intrinsics) to [fix] CCVER problem when using clang and cpu extensions (intrinsics)

Looks like CCVER configuration for clang misses a few things:

1. INCOPT needs "-isystem /usr/local/llvm37/lib/clang/3.7.1/include" as this is the place for files that clang needs to work with intrinsics.
2. INCOPTCXX needs "-cxx-isystem /usr/include/c++/5.0/backward" as libstdxx misses a few things (seen when compiling firefox).
3. gcc/gxx can be superseded too as some ports just hardcode compiler names. Thus:

    clang37_GCC=${clang37_CC}
    clang37_GXX=${clang37_CXX}

As clang struggles to be mostly gcc compliant there's nothing bad with it probably.

Ok, I'm trying to compile dri with clang37. When I setting CCVER to clang37 build stops on:

In file included from utils.c:37:
In file included from ../../../../../src/mesa/main/macros.h:36:
../../../../../src/util/rounding.h:33:10: fatal error: 'xmmintrin.h' file not found
include <xmmintrin.h>
        ^
        2 warnings and 1 error generated.

The file is present, but as per /etc/defaults/compiler.conf:

STD_INCOPT="-nostdinc -iprefix ${INCPREFIX} -iwithprefixbefore /usr/include"
DPORT_GCC_STD_INCOPTXX="-isystem /usr/local/lib/${CCVER}/include/c++ \
        -isystem /usr/local/lib/${CCVER}/include/c++/${MACHARCH}-portbld-dragonfly${MACHREL}"
DPORT_CLANG_STD_INCOPTXX="-cxx-isystem /usr/include/c++/5.0"

...

clang37_INCOPT=${STD_INCOPT}
clang37_INCOPTCXX=${DPORT_CLANG_STD_INCOPTXX}
