[Tinycc-devel] the format of the __TINYC__ macro should be documented

The TCC manual just says about the __TINYC__ macro: * '__TINYC__' is a predefined macro to indicate that you use TCC. But it actually contains the version, computed with sprintf(buffer, "%d", a*1 + b*100 + c); This should be documented (this is not obvious without reading the source si

[Tinycc-devel] aarch64: subnormal double to long double conversion bug

With TCC mob on aarch64, the double to long double conversion is buggy on subnormal values. This makes a MPFR test fail (reported by Christian Jullien). Testcase: #include int main (void) { volatile double d = 0x0.88p-1022; /* subnormal */ printf ("d = %a\n", d); printf ("d = %.40g\n", d
