similar to: [LLVMdev] What llvm tool will llvm-gcc call in each phase?

On x86-64 linux, in stage 2, I get: c++ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -o f951 \ fortran/arith.o fortran/array.o fortran/bbt.o fortran/check.o fortran/data.o fortran/decl.o

Hi everyone, Both llvm-gcc and clang would use llvm as its backend. Dose everyone know the difference of bitcode generated by llvm-gcc and llvm? Or actually they are same, like if I use the same compiler options, like -O4. Any help is appreciated. Best, Yuxi -------------- next part -------------- An HTML attachment was scrubbed... URL:

hi all, I'm working on scrapping some website data to build a database. Under most cases, I can use package XML to get the dataset. However, some of the website doesn't give a explicit address of the downloaded tables. To be more specific, for example, I'm interested in the website http://ets.aeso.ca/ The data we are scraping is the "Pool Weekly Summary" under the

Hi, all I use llvm-gcc -O4 to compile SPEC 2000, some benchmarks can't be built successfully, such as 164.gzip, 175.vpr etc. The error messages are as follows. .. zh.o unlzw.o unpack.o unzip.o util.o zip.o -o gzip bits.o: file not recognized: File format not recognized collect2: ld returned 1 exit status specmake: *** [gzip] Error 1 specmake options 2> options.err |

Hi, I have been trying to get to grips with GCC's specs language in order to add COFF and ELF emission options. I have noticed that the '-emit-llvm-bc' option does not appear to work at all either with -S or without, giving :- llvm-gcc: unrecognized option '-emit-llvm-bc' Also this seems by default seems for '-emit-llvm' to produce a '.o' file instead of

What are the current limitations of using -O4 in llvm-gcc-4.2? As a first test, I compiled the molscript program first as -O3 and it works fine. However if i try to compile the same code as -O4, the build fails with... ar -cru clib.a args.o str_utils.o dynstring.o err.o indent.o vector3.o matrix3.o quaternion.o body3d.o extent3d.o io_utils.o colour.o key_value.o named_data.o double_hash.o

Hi All, I am migrating a build system of an existing project from 'Object files' based executable generation to 'LLVM Bitcode' files based exe generation and applying OPT pass to LLVM Bitcode. I found out the following 4 step procedure. Please let me know if this is the right procedure or is there any other easy way of doing it. I need to modify 'Makefile' accordingly. I

Hi, Recently, I was looking into the bug #1227. I wanted to check if reordering optimization passes could solve it. To start with, I tried to reproduce the output of llvm-g++ -O3 using the combination of llvm-g++ -O0 and opt with the appropriate passes. However, I was unable to. I use SVN versions of llvm and llvm-gcc-4.2. First, I compile example.cpp (attached; taken from the bug #1227) with: $

For example, I have a webapp that handles /welcome. Does unicorn support to mount the entire webapp at /prefix so request to /prefix/welcome are?handled?

Hello, I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to .asm file. Basically assembly instruction file for my x86 backend. I think so we can use llvm-objdump. However I am not able to figure out its exact options. Could you please tell me how to do that? -- Thanks, Teja -------------- next part -------------- An HTML attachment was scrubbed... URL:

Thanks alot Chad for quick response. Does this means that, we can not use LLVM optimizations except O1, O2, O3, O4 and unroll-loops with clang? One more thing I would like to know that If I want to process multiple modules with opt at the same time like opt -adce *.bc then how is it possible with opt in one go, if I process all the bytecode files within Makefile. Thanks. Shahzad On Thu, Jun

Hi all, I have started using LLVM recently, and I have a basic question. There are two different ways in which an executable can be generated from a .c file - by just using llvm-gcc, and using a combination of llvm-gcc (to emit bitcode .bc), llc (to emit assembly code), as (to assemble the code) and collect2 (linker). For example, consider compiling test.c : 1) llvm-gcc -O3 test.c -o

Dear list, To make it easier, let me start with an example. Say I have 20 different cookies. Dave likes 7 of them, Evan likes 14 of them and Torri likes 11 of them. The data is cookies<-cbind(c(1:20), c(1,0,0,1,0,1,0,0,0,0,1,1,1,0,0,0,1,0,0,0), c(1,1,1,0,0,1,1,1,1,1,0,1,1,0,1,0,1,0,1,1), c(1,1,0,1,0,0,1,0,1,1,0,0,1,0,1,0,1,1,1,0))

Hi, I would like to get the whole program bitcode with debug information in it. I tried to use CFLAGS = "-O4 -g", but it ends with the following error: collect2: ld terminated with signal 6 [Aborted] Unknown constant!

Teja, Your mention of .s being bytecode confuses me, but if you're asking how to lower a bitcode (.bc) or IR file (.ll) to assembly (.s) than llc is the tool you are looking for. llc -O2 path/to/bitcode/input.bc -o output.s -Chris On Mar 7, 2013, at 10:39 PM, teja tamboli wrote: > Hello, > > I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to
