GCC compiler option as pragma

GCC compiler option as pragma

[Gautier write-only]

Hello,
It seems too easy to be asked... but is there any way to pass a GCC
compiler option through a pragma in a unit's source ?
TIA

I don't think so.

There is a way to pass *some* but not all options, namely those
controlling warnings (-ngtaw*), style checks (-gnaty*) and validity
checks (-gnatV*); see

http://gcc.gnu.org/onlinedocs/gcc-4.6.3/gnat_rm/Pragma-Style_005fChecks.html#Pragma-Style_005fChecks
http://gcc.gnu.org/onlinedocs/gcc-4.6.3/gnat_rm/Implementation-Defined-Pragmas.html#Implementation-Defined-Pragmas
http://gcc.gnu.org/onlinedocs/gcc-4.6.3/gnat_rm/Pragma-Warnings.html#Pragma-Warnings

And, of course, the language defined pragma Optimize and pragma
Linker_Options.
