------- Comment #21 from guenter at roeck-us dot net 2006-08-29 19:12 -------
This bug fix causes severe problems with all e500 double precision floating
point code. It generates code such as :
...
evldd 9,104(31)
stw 9,112(31)
stw 10,116(31)
...
i.e., the compiler believes that a floating point value is in (r9,r10),
while it is in LO(r9),HI(r9).
Evidence is that any glibc compiled with a gcc including the fix fails
all over the place. printf() of any float does not work. The fractional result
of modf() is bad, for example.
Just a heads up, I will try to submit a bug report after I find a simple test
case.
