New Revision: 40522
URL: http://llvm.org/viewvc/llvm-project?rev=40522&view=rev
Log:
Fix float initializers emission (HOST_WORDS_BIG_ENDIAN is obsolete).
We still need to verify stuff on big-endian targets and cross-compilation
on targets with different endiannes.
Also, make use of FLOAT_WORDS_BIG_ENDIAN, which seems to be important
for ARM.
This change allows most of SingleSource/Benchmark and some of
MultiSource/Applications to pass!
