1: /*
2: This file dispatches between various header files for blas/lapack distributions to handle the name mangling.
3: It also provides C prototypes for all the BLAS/LAPACK functions that PETSc uses
5: This is not included automatically by petscsys.h because some external packages include their own prototypes for
6: certain BLAS/LAPACK functions that conflict with the ones given here. Hence this should only be included when needed.
8: The BLAS/LAPACK name mangling is almost (but not always) the same as the Fortran mangling; and exists even if there is
9: not Fortran compiler.
11: PETSC_BLASLAPACK_STDCALL is for Microsoft Windows compiles, it also implicitly has capitalized function names
12: PETSC_BLASLAPACK_UNDERSCORE BLAS/LAPACK function have an underscore at the end of each function name
13: PETSC_BLASLAPACK_CAPS BLAS/LAPACK function names are all in capital letters
14: PETSC_BLASLAPACK_C BLAS/LAPACK function names have no mangling
16: PETSC_BLASLAPACK_SINGLEISDOUBLE - for Cray systems where the BLAS/LAPACK single precision (i.e. Fortran single precision is actually 64 bits)
17: old Cray vector machines used to be this way, it is is not clear if any exist now.
19: PetscBLASInt is almost always 32 bit integers but can be 64 bit integers for certain usages of MKL and OpenBLAS BLAS/LAPACK libraries
