The following setup on SL compiles R-devel and passes check.
C compiler: /Developer/usr/bin/llvm-gcc -std=gnu99 -m64 -O4
-Wall -fopenmp -mtune=native
Fortran 77 compiler: /usr/local/bin/gfortran-4.5 -m64 -O4 -Wall
-fopenmp -mtune=native
C++ compiler: /Developer/usr/bin/llvm-g++ -m64 -O4 -Wall
-fopenmp -mtune=native
Fortran 90/95 compiler: /usr/local/bin/gfortran-4.5 -m64 -O4 -Wall
-fopenmp -mtune=native
Obj-C compiler: /Developer/usr/bin/llvm-gcc -m64 -O4 -Wall
-fopenmp -mtune=native
This compiles at breakneck speed (compared to gcc-4.2 or gcc-4.5). In fact,
with recommended packages,
for all of R-devel:
time make -j8
real 2m33.028s
user 3m59.076s
sys 0m33.248s
NB: I still have problems with CC and OBJC equal to clang (from Apple)
or to clang (from the llvm svn), even without the -fopenmp flag.
