New Revision: 1278
Log:
* sysdeps/powerpc/powerpc32/e500/fpu/tst-spepim.c: New.
* sysdeps/powerpc/powerpc32/e500/fpu/Makefile: Enable new test.
* sysdeps/powerpc/powerpc32/e500/fpu/strtofix.c (STRTOFIX): Check
for invalid numbers starting "0x" with no following digits.
Correct exponent normalization for hex numbers. Correct handling
of low digits in hex numbers.
