Created a generic portmacro.h file in the CBMC include folder (#847)
* Created a generic portmacro.h file in the CBMC include folder instead of using the default MSVC-MingW one. This allows each proof to define the portmacro constants it needs and cover all code in the Task Scheduler * Removed the license text from the portmacro file * Fix CI checks Signed-off-by: Gaurav Aggarwal <aggarg@amazon.com> * Fix spell check Signed-off-by: Gaurav Aggarwal <aggarg@amazon.com> Signed-off-by: Gaurav Aggarwal <aggarg@amazon.com> Co-authored-by: Gaurav Aggarwal <aggarg@amazon.com> Co-authored-by: Gaurav-Aggarwal-AWS <33462878+aggarg@users.noreply.github.com>pull/850/head^2

/*
|
||||||
|
* portmacro.h is an architecture specific file defining certain
|
||||||
|
* constants and declaring certain functions.
|
||||||
|
*
|
||||||
|
* This portmacro file is defined in the CBMC directory and aims
|
||||||
|
* to be architecture-independent, with all constants defined with '#ifndef'.
|
||||||
|
* Hence, each proof can override the definitions they want to modify
|
||||||
|
* in the proof-specific makefiles and the remaining constants will take
|
||||||
|
* default values from the definitions in this file.
|
||||||
|
*
|
||||||
|
* The default values in this portmacro are a combination of the
|
||||||
|
* values from the portmacros of FreeRTOSKernel/portable/MSVC-MingW
|
||||||
|
* and FreeRTOSKernel/portable/IAR/ARM_CM33/non_secure.
|
||||||
|
* They cover almost all the constants needed in the kernel.
|
||||||
|
* If a specific proof needs some constant not available in this
|
||||||
|
* file, one can directly define the constant in that proof's makefile.
|
||||||
|
* To add additional constants to this file, use the '#ifndef' style
|
||||||
|
* from below to ensure that the constants can be overridden in
|
||||||
|
* specific proofs.
