*1. I have searched the access/setting of LLVMCC_EMITIR_FLAG in the build directory, recursively, and all the output is what I pasted in last email (just the same to the that in source directory). Maybe the configure failed to do it. My command list for building the test suit is as followings:* *(1) cd ~/SRC_DIR/llvm/projects* *(2) svn co http://llvm.org/svn/llvm-project/test-suite/trunk

Hi sir, I have built the test suits in following steps: 0. $cd LLVM_GCC_DIR; $gunzip --stdout llvm-gcc-4.2-*version*-* platform*.tar.gz | tar -xvf - 1. $cd SRC_DIR/llvm-2.8/projects 2. $svn co http://llvm.org/svn/llvm-project/test-suite/trunk test-suite 3.$cd OBJ_DIR; 4. $SRC_DIR/configure --prefix=INS_DIR --enable-debug-runtime --disable-optimized --enable-debug-symbols

I have built and configured the test suits as told at http://llvm.org/docs/TestingGuide.html#testsuite. The llvm is built with configuration: SRC_DIR/configure --prefix=INS_DIR --enable-debug-runtime --disable-optimized --enable-debug-symbols --enable-assertions This configuration is used again in the re-configure process. However, after the re-configure process, the following "make"

Please email the list, not me directly. Try doing a 'make clean' then a 'make VERBOSE=1' in the test-suite directory. -Chris On Jan 13, 2011, at 6:04 PM, Qingan Li wrote: > Hi Chris, > > [qali at qali SingleSource]$ llvm-gcc -v > Using built-in specs. > Target: x86_64-unknown-linux-gnu > Configured with: /home/nicholas/2.8-final/llvmgcc42-2.8.src/configure

Hal's advice helps me a lot to understand the implementation much better. Thanks so much! So, now I am able to state my problem more clearly: 1) There are two kinds of locals, i.e., the local variables originated from the source code (like C/C++), and the compilation generated temporaries. After instruction selection phase, the former is seen as frame indexes, while the latter is seen as

Hi everyone, we have several header files in which the NDEBUG macro is being used. In some of these, the NDEBUG macro changes the size, the interface, or the layout of a type. One example is AssertingVH, which turns into a flat, transparent Value* wrapper in Release build. Now everywhere you use these headers, the state of the NDEBUG flag must be the same, or else bad things could happen. This

Hi, While audit our code, we found out a strange pattern in one of the LLVM headers and we were wondering if that was expected or if it should be fixed. Namely the problem looks like this: #ifndef NDEBUG // Define some variable. #endif assert(/*use this variable, i.e., outside of the ifndef NDEBUG scope*/); This happens in include/llvm/IR/ValueHandle.h for the variable Poisoned line 494

Good point, I forgot to check the standard. Given the clang was failing I assumed the code was wrong x). I am guessing there is something weird with the project, because indeed, paragraph 7.2 of the standard says: The assert macro is redefined according to the current state of NDEBUG each time that <assert.h> is included. > On Oct 4, 2017, at 2:53 PM, Craig Topper <craig.topper at

Hi, Can anyone help me with the stack slot coloring optimization? This corresponding file is /lib/codegen/stackslotcoloring.cpp. It is said this optimization was for stack slot overlay for frame size reduction, after register allocation phase. And this transformation pass relies on the LiveStack analysis pass. How, when checking the source code, it seems the LiveStack analysis has not been

While we support compilation with CFLAGS=-DNDEBUG for the brave user desiring to avoid assertion overhead, this causes the tests to be less powerful. Fortunately, a quick test of './configure CFLAGS=-DNDEBUG' didn't hit any test failures, but it seems better to just ensure that assertions always work in our tests, even if they are turned off for the main binary.

It’s called “Not Debug”, but really it means “Assert > Disabled”. I think one could be forgiven for actually using it as a > heuristic of whether or not a build

When I searched for branch frequency profiling on the internet, I got this link by a casual chance: http://homepages.dcc.ufmg.br/~rimsa/tools/stprof-llvm.patch. It seems it was written by Andrei Rimsa. So I downloaded and integrate these files into the llvm-2.8 building. After the building, I tried "opt -static-profile bitcnt_1.bc", and an segment fault error occured. I debugged it

Hi all, During discussions about assertions in the Flang project, we noticed that there are a lot of cases in LLVM that #ifndef NDEBUG is used as a guard for non-assert code that we want enabled in debug builds. This works fine on its own, however it affects the behaviour of LLVM_ENABLE_ASSERTIONS; since NDEBUG controls whether assertions are enabled or not, a lot of debug code gets enabled in
