Hi, I was trying to use llc with soft-float option to generate soft-float code for Sparc. But it does not work. With or without -soft-float option will generate the same code for llc. Is this still an experimental feature? -- Xun Li Computer Architecture Lab Department of Computer Science University of California, Santa Barbara

Hi All, I am working on a custom defined architecture which implements Sparc ISA but without floating point instructions. I have two questions regarding using LLVM: 1. How to enable soft-float when building llvm-gcc? 2. How to let llvm-gcc generate native code (binaries) for Sparc? Do I have to compile glibc or newlib for Sparc and link with it together? I am kinda confused so it would be great

The documentation is correct, and the observation that the IR verifier is currently not verifying this property is also correct. Due to the way that dbg.declares are handled by later stages, LLVM can only keep track of one dbg.declare per variable and that is intentional. The dbg.declare intrinsic is supposed to pin a variable to a stack slot, such as in the code that clang emits at -O0. If you

How to enable soft-float when building llvm-gcc? There might be an option when configuring llvm-gcc. Check the GCC docs to see if such an option exists. Maybe

Hi, Guys: I'm new for LLVM. Just downloaded the LLVM. I used cmake to compiler the LLVM3.3, but found an error, because it can not automatically compiler the target description file (*.td) to the .inc file. But when I tried the LLVM 3.2, It is ok. Could your give me some suggestion? Regards' Xun -------------- next part -------------- An HTML attachment was scrubbed... URL:

hi all, I'm facing a problem with a brand new installation on fedora 9. packages were updated right after the installation, so the samba packages are of the latest available version (3.2.0-17.fc9). at the first run were created all the tree of tdb files under /var/lib/samba. now I create a new user: [root@barbara Scrivania]# smbpasswd -a barbara New SMB password: Retype new SMB password:

Hi, In the LLVM documentation it says "there can only be one call to llvm.dbg.declare for a given concrete local variable." However we don't seem to be checking it. opt tool can process IR that violates this rule without complaining. Is this intended, or is it a bug? What would be the consequence when this constraint is broken? -- Xun

I'm working on a program that loads several large data files. I'm using ddply (plyr is really awesome) but I want to minimize the amount of times a large data file is read in. One solution is to keep track of which data file is open with a global variable and then change the currently open data file globally as needed. However, I'm unclear on how to alter a global variable

Hi Just something that I have been finding very helpful sometimes when I am stuck with "how could I test this?" moments is looking at the Rails test suite. At the moment I am working on testing our custom error_messages_for methods and I have found looking at how the Rails tests in active_record_helper work helpful :-) So just thought I''d share that.

Hi Just a quick question .... what backward versions of Rails will the 1.1.0 versions of RSpec and Spec::Rails support? I think I maybe under the (incorrect) impression that I had to go to Rails 2.0 for 1.1.0 Cheers Shane Shane Mingins ELC Technologies (TM) 1921 State Street Santa Barbara, CA 93101 Phone: +64 4 568 6684 Mobile: +64 21 435 586 Email: smingins at elctech.com AIM:

Hi, I have been trying to figure this out for a long time and really need some help. I am compiling C programs which uses some math functions (such as pow, ceil) into SPARC ISA, using llvm-gcc. I imagine below is the right process: llvm-gcc -c -emit-llvm *.c llvm-ld -lm *.bc -o test llc -march=sparc test.bc -o test.s However when I look into test.s, I realized that those math functions are not

Hi We have specs in our rails project other than model/view/controller .. we have interests and lib ... using use_transactional_fixtures = true seems fine in a spec in the m/ v/c and interests directories but not in lib Just wondered if anyone had any quick thoughts as to why that may be???

Hi, I was looking into the implementation of TailRecursionElimination, and noticed that we have the constrain that if any call uses a local, even though it doesn't capture the local, it would still prohibit TCE. This contain seems unnecessary and overly limiting? Relevant code is here:
