You will need to install a cross compiler. I think you can find one somewhere in this link: https://sourcery.mentor.com/GNUToolchain/ Once you have a cross compiler, this should do what you want (if you want little-endian code): clang -target mipsel-unknown-linux -ccc-clang-archs mipsel -O3 hello.c -o hello.bc -emit-llvm llc -march=mipsel hello.bc -o hello.s mips-linux-gnu-gcc hello.s -o hello

There is also: 1) an alternate clang driver at http://code.google.com/p/alternate-clang-driver/ . This makes it more or less gcc compatible. 2) there is a way to invoke it all directly with just a call to clang as is with x86/linux but it's not totally finished. i will try and post something about this. the direct form will work if you are on a mips linux machine but there are still some

Thanks Akira, it worked!

Great Job! If I use alternate-clang-driver, will I need mips-gcc still? I mean alternate-clang-driver use as&ld directly or by calling gcc?

For compile and link Basicmath files (using shell script): llvm-gcc -emit-llvm basicmath_small.c -c -o basicmath_small.bc llvm-gcc -emit-llvm cubic.c -c -o cubic.bc llvm-gcc -emit-llvm isqrt.c -c -o isqrt.bc llvm-gcc -emit-llvm rad2deg.c -c -o rad2deg.bc llvm-link basicmath_small.bc cubic.bc isqrt.bc rad2deg.bc -o basicmath.bc

Ok! I do understand.

I have two values and I want see if them are equals. Then, I would a instruction like if Value1 != Value2, error without create a new block, continuing the execution in the same block, forcing the LLI to execute this. 2011/9/5 Eli Friedman <eli.friedman at gmail.com> > On Mon, Sep 5, 2011 at 4:47 PM, Rafael Baldiati Parizi > <parizi.computacao at gmail.com> wrote: > >

Hello, I created a new block for execution to continue, but I got the case in which a statement defined in a block is used in another, not dominate all uses. For example: entry: %n_addr = alloca i32, align 4 %retval = alloca i32 %"alloca point" = bitcast i32 0 to i32 store i32 %n, i32* %n_addr %0 = call i32 (i8*, ...)* @printf(i8* noalias getelementptr inbounds ([20 x i8]*

Ok.

Why do you want to reduce the number of LLVM IR blocks?

The definition of a "basic block" is a sequence of instructions with a single entry and a single exit.

I already did. What I need is to have this output in a txt file.

Yes, I've tried and it did not work On Tue, Jun 12, 2012 at 4:03 PM, Villmow, Micah <Micah.Villmow at amd.com>wrote: > Have you tried "opt -stats bitecode.bc > test.txt"?**** > > ** ** > > *From:* llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] *On > Behalf Of *Rafael Parizi > *Sent:* Tuesday, June 12, 2012 11:36 AM > *To:*

Hello, I would know how can I make a branch in llvm ir without a label of destination? For example: br i1 %1, label %bb, *NO LABEL HERE* * * Thanks! -- *Rafael Parizi* -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I'd like to know if is possible to create a new entry block and a branch to old entry block? How can i make this?

Add an optimization level and you get information.

You can't do that; a br instruction must be at the
