TI C6000 compiler is there a warning for reordering like in GCC -Wreorder

This diagnostic is classified as a remark by default, so you need to activate all remarks with the -pdr option:

cl6x file.cpp -pdr -pden
"file.cpp", line 3: remark #1988-D: the initialization of member "a::x" will be done before that of member "a::y"

or turn this one remark into a warning with the -pdsw=1988 option:

cl6x file.cpp -pdsw=1988 -pden
"file.cpp", line 3: warning #1988-D: the initialization of member "a::x" will be done before that of member "a::y"

Hi,

I tried your suggestion and have the following flags enabled when compiling:

  COMMON_CFLAGS:= --gcc --silicon_version=6740 --abi=coffabi --display_error_number --  
    define=DSP=1 --display_error_number
  CFLAGS:=$(COMMON_CFLAGS)
  CXXFLAGS:=$(COMMON_CFLAGS)
  LDFLAGS:=--warn_sections --reread_libs

COMMON_FLAGS:=--asm_directory=$(O)/$(1) --temp_directory=$(O)/$(1) --pp_directory=$(O)/$(1) --obj_directory=$(O)/$(1) \
--issue_remarks -pdsw=403 -pdsw=880 -pdsw=230 -pdsw=1988 -pdsw=342 -pdse=238 -pds=681

Question 1: I'm using c6x version 7.4.2 toolchain is this diagnostic number present in this compiler?
Question 2: can i suppress warnings generated by TI sytem headers like the following warning:

/data/tools/C6000CGT-7.4.2/include/limits", line 723: remark #195-D: zero used for undefined preprocessing identifier

Remark: When enabling all remarks with --issue_remarks (leaving out -pdsw, -pds, -pdse) i don't see the reordering warning. However when i compile my class with a normal GCC compiler it immediately displays the warning.

Hope you can help to enable more warnings in the c6x complir,

Thanks in advance,

Rob

No.  No current release of the C6000 compiler supports this diagnostic.  It will be supported in the next major release of the C6000 compiler.  According to here, that is version 7.6.0, scheduled for the end of March.

Yes.  To do it from the command line use -pds=195.

Thanks and regards,

Thanks for your reply i will wait for the 7.6.0 releases before upgrading, for now i will verify the warnings in my classes using gcc x86.

Question3:  -pds=195 also suppresses these remarks in my own code as well. I was wondering if the TI toolchain could ignore warnings generated by the TI system headers which i did not create. 

For instance GCC ignores warnings generated by theses headers so meaningfull warnings of the user-code are visiable and not clouded by systemheader warnings.  See http://gcc.gnu.org/onlinedocs/cpp/System-Headers.html

Thanks for your reply,
