llvm dev - Feb 2009 - [LLVMdev] llvm-gcc (pre-release and svn sources) fails to compile on Solaris10/SPARC

I am new to LLVM, and I'm trying to compile llvm and llvm-gcc from
subversion on a Solaris10/SPARC machine. I have already tried building
llvm-2.4 on this machine, but it failed.

I then tried the subversion sources (rev. # 65253 fro llvm and
rev#65263 for llvm-gcc) and llvm at least builds correctly ( I however
have not tried testing it!). I can execute binaries located in
llvm-objects/Release (I built a Release version as instructed by
llvm-gcc README).

Since then I am trying to build llvm-gcc and it fails all the time. I
tried building llvm-gcc from svn and 2.5 pre-release. I also tried
building llvm-2.5 pre-release and that succeeds but llvm-gcc-4.2-2.5
pre-release fails again. I have listed below my machine config and the
errors reported by make in each case.

I am not sure if I should file a bug, hence I'm posting this here.
Looking forward to possible solutions.

thanks,

I don't have access to a Solaris10 machine, can you propose a patch  
that fixes it for you?

That's correct. There was a bug fixed after 2.4 release.

afair solaris always had a special gcc build procedure. I can confirm,  
however, that sometime between 2.4 and 2.5 I built cross llvm-gcc for  
sparc-elf (with newlib) and at least it was bult successfully. In any  
case, result of codegen is not fully ABI-compliant.

That's something strange. Are you sure you didn't mixed sources from  
release and some older / newer version? What is gcc version on your box?

You can install dejagnu, and run 'make check' in the llvm objdir.
All tests except one pass for me on Solaris10/x86 (LLVMHello.so is not
copied to the correct location for some reason, so that test fails),
it would be interesting to see what happens on Sparc.

Wow, where did you get a 4.3.x compiler for Solaris? Latest I've seen
packaged are 3.4.x and 4.0.x.

I tried building on Solaris10/x86, and I had to use something like
--with-as=/usr/sfw/bin/gas --with-gnu-as --with-ld=/usr/ccs/bin/ld
--without-gnu-ld.

However it failed with an undefined reference to 'copysignl'.

hmm ... that's disheartening to hear. I intend to use the code
generated by LLVM to run on a full system simulator, so now I don't
know how that will pan-out. I don't want to loose out on LLVM's
strengths in static analysis just because I'm tied to a particular
ISA! Let's see how it goes ....

I compiled gcc from sources and here's the config>>

Using built-in specs. Target: sparc-sun-solaris2.10 Configured with:
../gcc-4.3.2/configure --prefix=/usr/local/gcc-4.3.2
--with-gmp=/usr/local --with-mpfr=/usr/local Thread model: posix gcc
version 4.3.2 (GCC)

and I'm pretty sure I did not mix any sources.

also, are there any instructions you have about cross compiling
llvm-gcc? I plan to use an x86_64-linux box as host and a
sparc-solaris10 box as target (I can get all the platform specific
headers and libs fro my host target easily). also, since I want to
compile llvm-gcc front-end, would I need to compile binutils etc. for
my target? where there any specific issues that you faced? how did you
test your front-end?

My other option is to compile llvm and llvm-gcc on a sparc-linux box
(I currently have a sparc64-linux box, but LLVM doesn't support that
target). Have you heard of any success story for llvm-gcc on
sparc-linux? I am a bit hesitant on that coz the llvm docs page does
not mention if this config has been tested.

I am totally inexperienced with testing using dejagnu, but here's the
output summary that's dumped on my screen >>
                ===  Summary ==

I see a lot of "FAIL:" messages, and they are somehow always related
to -march=x86 flag for llc. Following is an example of these kind of
errors>>

I'm not really sure what's going on! It'd be great if soemone can
provide some insight into this for me.
