Hi, I noticed one class in MipsInstrFormats.td:L46 -> Class MipsPseudo. I wonder whether I can use this. If does, I wonder what would be the right way to use.

Hi, In order to emit "la $4,ADDR" instead of lui followed by addiu to load the data address, could you advise what is proper way to revise td files in the MIPS target?

I don't think I ever said that the MIPS target is broken. I am simply trying to branch out one additional llc target for SimpleScalar PISA architecture.

I reiterate. You should fix the simulator. It is broken. The compiler is not. Fix what's broken. -Jim On Oct 7, 2011, at 1:11 PM, Gang-Ryung Uh wrote: > Hi, > > I noticed one class in MipsInstrFormats.td:L46 -> Class MipsPseudo. I wonder whether I can use this.

Do you want to replace lui $2, %hi(g1) addiu $2, $2, %lo(g1) with this? la $2, g1 If that is the case, you can add this pattern. def op_la : Operand<i32>; def LA : FI<0x09, (outs CPURegs:$dst), (ins op_la:$addr0, op_la:$addr1), "la $dst, $addr0", [(set CPURegs:$dst, (add (MipsHi tglobaladdr:$addr0), (MipsLo tglobaladdr:$addr1)))], IIAlu>;

Hi, I wonder what PRE algorithm is used for the GVN.cpp in LLVM. Any reference will be appreciated. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20140930/3d7f74e3/attachment.html>

Hi, for our micro-architecture research, we are using simplescalar 3.0 32bit mips simulator, which comes with binutils 1.5.2, and the ld fails at "lui" (bfd error). However, the ld is happy with "la" (assembler macro) and simulator correctly simulates.

Hi, We have tried and generate assembly code for very simple test C code. But, binutils-2.5.2 (simplesim-3.0) cannot handle the produced assembly code with the following complaints. Could you advise which version of bitutils that we need to use for mips code with LLVM with Clang? Thanks, $ GCC addr01.s addr01.s: Assembler messages: addr01.s:1: Error: Unknown pseudo-op: `.section'

We are trying to use LLVM (Clang as the C frontend) to generate code for 32-bit MIPS (little-endian)l, which can run on simplescalar 3.0 sslittle-na-sstrix platform. Can you advise what would be the right way to use the LLVM compiler infrastructure? The following is the one I used, but it appears that it produce the code in big-endian (and I wonder whether the calling convention is right.) To

It will produce little-endian code if you replace "mips" with "mipsel". 1. clang -ccc-host-triple mipsel-unknown-linux -ccc-clang-archs mipsel -O3 -S -emit-llvm foo.c -o foo.ll 2. llc -march=mipsel -mcpu=4ke foo.ll -o foo.s (the -march option is redundant) If you do not specify the target cpu with -mcpu, by default it will generate code for Mips1, which has not been tested as

Hi, We would like to assemble .s file using binutils-2.5.2 which comes with simple-scalar3.0. Unfortunately, this particular version of binutils doesn't seem to handle global-offset-table (position independent code) and the some of the mips instructions.

We are using simplescalar 3.0 as an architecture simulation platform for our research. The current version of the simplescalar still uses gnu binutils 1.5. and gcc-2.7.2 to generate 32bit mips code. We are currently trying to replace gcc-2.7.2 by LLVM current. However, the generated code cannot be processed by this old binutils-1.5. We expect that it can be quite difficult to make simplescalar use

Hi, Target architecture for llc can be specified using -march, -mcpu, -mattr options. Is it possible to override target CPU attributes when using llvm-gcc compiler? Regards, Sergey Y.

Is it possible to configure llc to generate code for other architectures? For instance, what I need to do to generate Sparc machine code?

Hi there! I need some assistance here with vector orderings. I have a set of q vectors of length p, grouped by rows in a matrix A, q?p, that I need to order lexicographically (http://en.wikipedia.org/wiki/Lexicographical_order). I also have another matrix B, p?r, and a vector c, that should be ordered according to the order of A. So far, I was doing ordering <-

Hi! Maybe this is a silly question, but I need the column rank (http://en.wikipedia.org/wiki/Rank_matrix) of a matrix and R function 'rank()' only gives me the ordering of the elements of my matrix. How can I compute the column rank of a matrix? Is there not an R equivalent to Matlab's 'rank()'? I've been browsing for a time now and I can't find anything, so any

Hi! I want to plot three graphs (residuals, ACF and PACF of a model). Ideally I would use a c(2,2) disposition where the residuals plot would start at position 1,1 and span to position 1,2. Then I would plot the ACF in position 2,1 and the PACF in position 2,2. Maybe is clearer like this: -------------------------- | | | residuals | |
