Hi, I thought to update my newlib-1.8.0-based ppc-eabi-target libs to newlib-1.8.1. So I built them first with an up-to-date gcc-2.8.1 snapshot (980513), found weird printf() output from my normal test routine, 'testprintf.c', from the glibc-1.0.9 sources, and tried with the other ppc-eabi-target compilers I have (egcs-1.0.3, 2.8.1, 2.7.2-970404)... But for every combination of all the compilers & newlib compiled with any of these, I got the same results... Building newlib-1.8.0 with any of these gave an acceptable output with all the compilers however. So, a new bug seem to be invented to newlib-1.8.1 ;-) I used the 'psim' simulator to check the compilers & libs. Here are the non-working cases extracted to a test program : --------------------------- #include <stdio.h> #include <float.h> int main() { double d = FLT_MIN; printf ("%.17e\n", d / 2); printf("g-style big:\t\"%.60g\"\n", 1e20); printf ("%15.5e\n", 4.9406564584124654e-324); exit (0); } ------------------------------------ The newlib-1.8.0 output (right?) : --------------------------------------- 5.87747175411143754e-39 g-style big: "100000000000000000000" 4.94066e-324 --------------------------------------- and the newlib-1.8.1 output : --------------------------------------- 7.71322248847063567e-39 g-style big: "096833364535605198848" 0.00000e+2147483646 --------------------------------------- Has someone already found a fix to this, or should I start try to track it... Those having built newlib-1.8.1 for some other targets: Does this program work with your system? (I'll look this with other targets too...) Regards, Kai
