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
4 
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.
7 
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.
10 
11   PETSC_BLASLAPACK_UNDERSCORE BLAS/LAPACK function have an underscore at the end of each function name
12   PETSC_BLASLAPACK_CAPS BLAS/LAPACK function names are all in capital letters
13   PETSC_BLASLAPACK_C BLAS/LAPACK function names have no mangling
14 
15   PETSC_BLASLAPACK_SINGLEISDOUBLE - for Cray systems where the BLAS/LAPACK single precision (i.e. Fortran single precision is actually 64-bits)
16                                     old Cray vector machines used to be this way, it is is not clear if any exist now.
17 
18   PetscBLASInt is almost always 32-bit integers but can be 64-bit integers for certain usages of MKL and OpenBLAS BLAS/LAPACK libraries

33     PetscCallBLAS - Calls a BLAS or LAPACK routine so that the stack trace returned from any signal received includes the name of the BLAS/LAPACK routine
34 
35     Synopsis:
36    #include <petscsys.h>
37    void PetscCallBLAS(char *name,routine)
38 
39     Not Collective
40 
41   Input Parameters:
42 +   name - string that gives the name of the function being called
43 -   routine - actual call to the routine including its arguments
44 
45    Level: developer
46 
47    Developer Notes:
48    This does not check error codes returned from the BLAS/LAPACK routine or ever return from the current subroutine. It merely pushes onto the PETSc
49    stack the name of the BLAS/LAPACK routine before calling the routine and removes it after a successful call.
50 
51    LAPACK routines that return info codes should be followed by
52 .vb
53    PetscCheck(!info, PETSC_COMM_SELF, PETSC_ERR_LIB, ...)
54 .ve
55 
56    This macro exists so that when a BLAS/LAPACK routine results in a crash or corrupts memory, they get blamed instead of PETSc.
