History of the WMC tool

v1.0

added Unident mode to remove unused left margin
added automatic conversion of TABs to spaces
added a command-line switch to disable all warnings (/dw99)
modified the atomatically-generated file "wmc_auto.h" to eliminate warnings when compiled with gcc
removed #pragma WMC_TOOL_MESSAGE in the rom_*.c files
removed #pragma WMC_TOOL_MESSAGE for manually-instrumented sections
changed the default PROM counting weights to those specified in [S4-110479 - FTO - On Program ROM measurement for EVS standardization.doc] ([https://www.3gpp.org/ftp/tsg_sa/WG4_CODEC/TSGS4_64/docs/S4-110479.zip)
fix of a small bug where using /op2, /op3 crashes the WMC tool
added support for Windows 8 command line and Cygwin V1.7.17 and later versions
fix for a bug where a $("[]M[]") was inserted at the end of some C source files when it was re-instrumented

break in early-return out of .each early with return false
prevent adding unnecessary space by the functions Move_on_Chars() and Skip_Chars()
optimize the function Find_Region() to improve the speef of instrumentation
optimize the function calculating the next pointer address after hitting the search target
order macro names, system functions, etc. in the highest priority order
combine strlno and strcno inside Make_Position_String()
optimize the usage of the function Instrument_Names() inside Find_Keywords() and Find_Calls()
remove the cases where item_link is always NULL

first version uploaded to the Open-ITU/STL Github repository
remove obsolete parts of the source code (e.g. FLC)
bug in PROM calculation fixed
command-line options modified (/ic and /op removed)
memory instrumentation (PROM, Table ROM, static RAM and stack) integrated within the WMC tool (auxiliary files PROM_Size_xxx.c no longer generated)
merging and renaming of files: ** wmops.h and wmops.c -> wmc_auto.h and wmc_auto.c ** memory.c -> wmc_auto.c ** mem_count.h and mem_count.c -> wmc_auto.h and wmc_auto.c ** wmc_auto.h and wmc_auto.c are optionally generated by the WMC tool with the ./wmc_tool /cp dir_name command-line option
PROM consumption calculated during instrumentation and added at the end in each .c file
total PROM consumption may be printed with the function print_mem()
re-factoring of the Table ROM instrumentation, calculation and reporting

fixed compilation issues on MaC platforms
fixed a problem where NaN was printed for a non-instrumented function having zero complexity
dynamic allocation and re-allocation of all internal buffers tracking both heap and stack call trees
introduction of -f FRAME_PER_SECONDS command-line option allowing the user to choose the number of frames per second (default is still 50.0)
fixed a problem when push_wmops() was called twice when WMOPS_DETAILS was activated
raise an error message if #define WMC_TOOL_SKIP is not paired with #undef WMC_TOOL_SKIP
export information about all dynamic allocations/de-allocations occuring during the runtime of the codec to a .csv file
added an exemplary Python script mem_analysis.py for graphical analysis and profiling of dynamic memory alloations based on the generated .csv file
added support for counting complexity and PROM size of BASOP operations and BASOP functions within floating-point source code

added the -s (--skip_cmplx_instrumentation) command-line option, which avoids the instrumentation of function bodies. The func_start_ and return_ keywords, along with the remaining functionality, remain unchanged.

fixed instrumentation issues in encoder.c of the 3GPP EVS codec where malloc() is instrumented and print_mem() is present as well
when #undef WMC_TOOL_SKIP is missing, automatically assume end of file, but before the last automatically instrumented segment
the function DesInstrument_ROM() is called in all regular files as well as the file pointed to with the -m command-line argument
