I realize that I should get a --disable-jit version running before tackling this, but since I stumbled into it last night...
In jitinline.c, at line 1834, there is code for generating a JIT-ted version of char->integer. I think I understand all of it, except for line 1851: 1851: jit_movr_p(dest, JIT_R0); If the initial test (at line 1846 succeeds, then we jump past this instruction (although we might jump back later, if the type-tag test (at 1853) fails (well, succeeds, I suppose). But, if we ever get to the code at line 1849: (void)jit_calli(sjc.bad_char_to_integer_code); Then we're never going to return from there... I think. So, I'm not sure what execution path the code could take where that move instruction would matter. Also, assuming that instruction is reachable, I still don't know what it's for. Can anyone (probably Matthew) enlighten me? -Jon _________________________ Racket Developers list: http://lists.racket-lang.org/dev
