Browse Source 
* What's new in AOCL 3.1

1) AMD BLIS:
    1.a) Supports Dynamic Dispatch and AOCL Dynamic feature
    1.b) Improvements in DGEMM, ZGEMM, DTRSM, DSYRK, xGEMV, and DOTV
2) AMD libFLAME:
    2.a) Supports LAPACK 3.10.0 specification
    2.b) Optimized factorization and ZGEEV routines
3) AMD FFTW:
    3.a) Features like 'AMD application optimization layer', 'Fast MPI transpose algorithm' and 'Top N planner' are added
4) AMD LibM:
    4.a) Optimized exp2, log2 (Single and Double precision) scalar and vector
    4.b) Optimized log10f (scalar and vector) and powf vector variants to support WRF4.1.2 benchmark
5) AOCL-Sparse:
    5.a) New API for sparse matrix and dense matrix multiplication
6) AMD ScaLAPACK:
    6.a) ILP64 support has been enabled
7) AOCL enabled MUMPS library:
    7.a) CMake based build system on Windows for AOCL enabled MUMPS sparse solver library will be available shortly on GitHub
        7.a.i)	Refer https://github.com/amd/mumps-build
    7.b) Spack-based recipe on Linux for AOCL enabled MUMPS sparse solver library will be enabled shortly

* Fix invalid version range error

* Incorporated review comments

1) Restore to previous url value
2) Instead of if else statements, used spack's enable_or_disable feature

* Incorporated following review comments:

1. Use of satisfies() for spec checks
2. Seperate conflict statements to check for minimum and maximum GCC versions
3. Used CMakePackage helpers
4. Code rearrangement to have the directives listed before methods
