I don't know if this would be called a bug, and I apologize if it's already been posted (searching turned up nothing), but I thought it might be worth reporting this discrepancy between the compiler and the included libraries.
OS: Windows XP Home SP2 and Pro SP2 tcc: 0.9.23 (taken straight off the web site http://laurenssimonis.com/tcc/tcc-0.9.23.zip) The following program fails to compile with the error "unknown constraint 't'". ---------------------------------------------------- /* asmt.c */ /* Result when trying to compile: > tcc asmt.c -Iinclude asmt.c:288: unknown constraint 't' */ #include <math.h> int main(int argc, char **argv) { double d = sqrt(-1.0); int i = isnan(d); return 0; } ---------------------------------------------------- The problem lies in the inline __asm__ in math.h. A handful of the functions use the 't' constraint, which unfortunately isn't handled by tcc. __fpclassify() __isnan() __isnanf() __signbit() __signbitf() __fp_unordered_compare() The current tarball code at http://landley.net/hg/tinycc doesn't appear to handle the 't' constraint either (tinycc-3e7c64539eb2). _______________________________________________ Tinycc-devel mailing list Tinycc-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/tinycc-devel
