GCC testresults from CVS version 980404

GCC testresults from CVS version 980404

[Andreas Jaeger]

I made a checkout around 8am GMT on 4th of April 1998 and compiled
egcs on i486 with Linux 2.1.92 headers, Linux 2.0.33 kernel, glibc 2.1 
snapshot, binutils 2.8.1.0.24.

I received the following errors:

I've checked the first failure with gdb and have appended the output.
I hope this is useful for somebody.

Following an advise by Martin von Loewis I run cc1 in the debugger
(after rebuilding egcs with CVS version from 980406) on the cpp output:

The input file is just:
$ cat 980226-1.i 
# 1 "/mnt/cc/egcs/egcs-cvs/gcc/testsuite/gcc.dg/980226-1.c"
 
 

extern double bar (double);

int
baz (double d)
{
  double e = bar (d);
  asm volatile ("" : : : "st");
  return printf ("%lg\n", e);
}

I'm using a recent glibc 2.1 snapshot on i486, Linux 2.0.33 kernel,
2.1.92 header files.
