Hi! https://github.com/seyko2/tinycc/commit/086ae74b696b7e2a73980bd852516b84251bd553 don't accept 0x123e-3 float format. This allow to compile tccboot kernel with a macro expansion like __asm__( "pushl $""0xfe""-256\n\t" );
No, simply fix the TCC bug. 0xfe+1 (and similar) simply is no valid token. Look at parse_number for inspiration (hint: remember the base and accept 'e'/'E' only if base is 10).
Ciao, Michael.
