Summary0000261: Frama-C fails to parse a file
DescriptionIt compiles fine with "gcc -I. -I./libtomcrypt/src/headers/ -DDROPBEAR_SERVER -DDROPBEAR_CLIENT dbutil.c -c -o dbutil.o" But when given to Frama-C (CPP is set accordinly), I get the following error: libtommath/tommath.h:77:[kernel] user error: GCC width mode TI applied to unexpected type, or unexpected mode In tommath.h line 77 we have a mysterious GCC incantation (>_<): typedef unsigned long mp_word __attribute__ ((mode(TI)));
Additional InformationUploaded a preprocessed file: "gcc -I. -I./libtomcrypt/src/headers/ -DDROPBEAR_SERVER -DDROPBEAR_CLIENT dbutil.c -C -E -o dbutil.i"
TagsNo tags attached.

those gcc attributes are very scarsely documented. The best pointer I've found so far is here:

I did end up at the same web page, I guess the idea was to define a 128-bits unsigned integer. I tried to replace it with __uint128_t but since it's a gcc internal and it is not defined in any .h file, Frama-C didn't like it either. However, both 'mode(TI)' and '__uint128_t' are only accessible through a 64-bits gcc, so I guess I'm back to 32-bits for now.
