System headers are not warning free when using qinfo=all with XL C/C++ compiler

When checking our own C/C++ source code I wanted to see strict warning checking behavior, to improve our source code. When using -qinfo=all a lot of warnings are raised by both C and C++ compiler. This RFE just shows a simple example for the C com...

Compile line -D function-like macro

An enhancement to the XL C/C++ for AIX compiler is requested to allow function-like macros to be specified on the compile/command line with the -D macro option. The macro would be specified like: -D"FUNC(a)=3+(a)"

xlc support for __attribute__((__deprecated__))

Add support for the GNU GCC __deprecated__ function attribute to allow in-source flagging of deprecated functions. The feature outputs a warning message during compilation for any usage of the function (with filename/line number) and where the dep...

Add option to reduce error from severe to warning when using -qcheck compiler option

We'd like a way to be able to reduce a particular error from Severe to a Warning so that compiles will proceed. SAS is interested in using the XL C/C++ compiler option -qcheck=bounds; however, SAS has a lot of legitimate legacy code that trips ove...

Provide option to disable -q'info' warnings for system headers.

XL C/C++ will issue many warnings about poor coding constructs in the xlc and AIX system header files. This makes it difficult to find warnings about our custom code and prevents usage of -qhalton for errors we deem important. Obviously, it would ...

Use of trigraphs in C++ Standard Library headers prevents disabling their use in custom code.

xlC -q'notrigraph' impossible to use in any program using C/C++ Standard Library headers. The IBM XL C/C++ headers use trigraphs. This is an archaic feature that we want to not allow in our source code. Unfortunately, use of -q'notrigraph' is not ...
