[LLVMdev] Error when running llc to compile .bc to .s

[hc2428 at columbia.edu]

Dear staff,

     I downloaded an llvm version from the svn trunk at June 12,  
because the released 2.5 version can not support "gcc -g -Ox", and  
x=1,2,3. I use the version in svn to compile an httpd.bc file  
succefully with dbgstoppoint() functions. However, when I use llc to  
compile the bc file to .s file (llc -f -o httpd.s httpd.bc), I met  
this error (the httpd.bc file will be attached at the next email):
