When running Enquire.efi, several errors similar to the following are produced:
Maximum exponent = 128
Maximum number = 3.40282347e+38
*** WARNING: Possibly bad output from printf above
expected value around 3.40282347e38, bit pattern:
11111111 11111111 01111111 01111111
sscanf gave -inf, bit pattern:
00000000 00000000 10000000 11111111
difference= inf
Overflow doesn’t seem to generate a trap
The memory allocation tests will also fail, sometimes leaving all available memory consumed.
The correct output in the above example is:
Maximum exponent = 128
Maximum number = 3.40282347e+38
Overflow doesn't seem to generate a trap
The root cause is that all operations on values of Long or ULong type, within the gdtoa library, must be 32-bit operations. A previous change replaced the Long and ULong definitions with INTN and UINTN, respectively. While this is correct for a lot of Linux and NetBSD code, it was not correct for this library.
This fix reverts the definitions of ULong and Long back to 32-bit types.
A descriptive comment has also been added to the U union.
Additional white-space has been added to tidy up the definitions of the word0 and word1 macros.
Verified with Enquire.efi and the ISO/IEC C Library compliance Validation Suite.
