Hi,
Not sure if this really helps, but I suppose it cannot hurt. All of the
remarks concern the build environment rather than the source/tools.
Nothing major except the last point which I suspect to be an error
on my side.
1) platform details from "configure"
2) source & output dir tree structure
3) sequence of actions
4) report
Hope this helps
Regards
Mark

4) report
- From the readme's FAQ and docs it is not so clear that there is a circular
dependency between llvm and llvm-gcc, to save recompile in (3) one ought
to use "./configure" already with "--with-llvmgccdir"
- after llvm configure, the makefile as a linker option incompatble with gcc
4.3.4
it suggests to change:
#RDYNAMIC := -Wl,-export-dynamic
RDYNAMIC := -Wl,-export-all-symbols
- llvm configure reports:
mmap() of a fixed address is required but not supported
it does not seem to be a requirement as the build process succeeds though
- the llvm build process has intermittent errors with conftest.c or contest.exe
being unaccessible
my guess is that the cygwin emulation is a bit slow and that the processes
does not wait
to check for the status of the files
-> As certain tests fails but configure completes succesfully I have no idea
on the impact
- the llvm-gcc build process has MANY intermittent errors with conftest.c or
contest.exe being unaccessible
probably same reason as above. here the build process terminates in error but
restarting (quite a few times)
results in a (apparently) operational llvm-gcc (compiles hello.c & llvm
--help gives proper version)
- the llvm-gcc build process fails regurarly, but not systematically, on a gcc
test
"can gcc produce an executable ... No"
typically at the later stages
- running the tests in .../projects/llvm-tests fails systematically
make cannot resolve *.rbc dependencies in the first single source test
- running the hello.c test (from the web tutorial) produces hell.exe and
hello.bc, but not "lli hello.bc" (see below)
lli cannot find "put()" (cannot find the dynamic lib containing "put()") I
may have simply missed a cygwin
specific dynamic link flag / configure option (the web doc make mention of
dynamic linkage on cygwin with
the platform notes, so perhaps this is what's meant)
