[LLVMdev] 'make check' failed with: ... PHI node entries do not match predecessors! ...

[Henrik Bach]

Hi,

Now, I've build the tools and the cfe. However, 'make check' gave me the 
attached results. Summarized as follows:

# of expected passes		1081
# of unexpected failures	26
# of expected failures		32

I configured llvm with following options: '--prefix=/home/hb/llvm/ 
--enable-targets=host-only'. I used gcc version 3.4.2 to build the tools and 
cfe. The cfe is version: llvm-gcc (GCC) 3.4-llvm 20030924 (experimental).

Especially I noticed this one:

--------------------

What went wrong in my build/test? I assume that the other errors are ok, due 
to I've only had build for the host-only architechture:
