I am getting the error above when I type "make all". "$LLVMCONFIG --version" shows 14.0.6.

Have you seen this error or fixed it? Thanks in advance.

The attached file executes instantaneous when compiled with clang while executed for 20 minutes before killing it when compiled with jlc.

Alias analysis crashes if a locationSet contains only DummyLocations. DummyLocations are skipped when memoryNodeMap is populated in ConstructPointsToGraph. As a consequence FindModuleEscapingMemoryNodes crashes when trying to access the map for the "dummy" locationSet.

As far as I can tell this can be fixed by either checking if the set is a key of memoryNodeMap and continuing otherwise, or by accessing memoryNodeMap even for DummyLocations.

This can be reproduced by running
jlc jlm-eval-suit/hls-test-suite/src/test-array.c followed by jlm-opt --llvm --AASteensgaardBasic -o /tmp/tmp-test-array-jlm-opt-out.ll /tmp/tmp-test-array-clang-out.ll (the -J option to explicitly specify jlm-opt passes in jlc seems to not be implemented)

jlc -DNDEBUG -w -Werror=date-time '-DVERSION="1.00"' '-DCOMPDATE="today"' '-DCFLAGS=""' '-DHOSTNAME="thishost"' -o mason.c.o -c mason.c

Adding -03 to the above line gives the following error: terminate called after throwing an instance of 'jive::compiler_error' what(): Invalid operand region. Aborted (core dumped)

jlc -O3 mason.c.o -o mason

clang: warning: mason.c.o: 'linker' input unused [-Wunused-command-line-argument] clang: warning: argument unused during compilation: '-emit-llvm' [-Wunused-command-line-argument] terminate called after throwing an instance of 'jive::compiler_error' what(): Invalid operand region. Aborted (core dumped)

Must have deleted a line by mistake when adding the previous changes as to commits. The opts.jlmopts was never set in cmdline.cpp so didn't matter if -J was specified for jlc.

Port of jlm to work with LLVM 10. Added MaybeAlign to memory operations. Added llvm fneg support to libjlm's ir operators.

All checks pass and the complete polyench.

Based on the make-targets branch.

These changes address most warnings from clang but maybe should be solved differently. So this is to start the discussion on how the warnings should be addressed.

The file endings in jive has been renamed to .hpp and .cpp from .h and .c, which required all includes in jlm to be updated and a make target for %.c to be changed to %.cpp

Commands for replicating the error jlc -I$(CSMITH_HOME)/runtime -O test-wrong-result.c -o test.jlc; clang -I$(CSMITH_HOME)/runtime -O test-wrong-result.c -o test.clang; ./test.jlc > jlc.output ./test.clang > clang.output diff jlc.output clang.output

jlm-print crashes when inputting the floyd-warshall benchmark from the polybench-jlm benchmark suite if it is first optimized with jlm-opt, and subsequently clang-opt at optimization level -O2.

Steps to reproduce:

clang -S -emit-llvm -Xclang -disable-llvm-passes -o fw.ll medley/floyd-warshall/floyd-warshall.c -Iutilities
jlm-opt --llvm fw.ll > fw-jlm.ll
opt -S -O2 -o fw-opt.ll fw-jlm.ll
jlm-print --j2rx --file fw-opt.ll > fw.xml

Terminates with the following stack trace:

terminate called after throwing an instance of 'jlm::error'
  what():  invalid type.

jlm-print crashes on programs compiled with certain optimizations enabled, such as -loop-unroll. However, this happens only after it the bytecode is passed through jlm-opt, even when this is run without performing any optimizations.

Tested on programs from the polybench benchmark suite: https://github.com/phate/polybench-jlm.

Steps to reproduce (requires both the jlm-opt and opt steps in this specific order to crash)

clang -S -emit-llvm -Xclang -disable-llvm-passes -o 2mm.ll linear-algebra/kernels/2mm/2mm.c -Iutilities
jlm-opt --llvm 2mm.ll > 2mm-jlm.ll
opt -S -loop-unroll -o 2mm-opt.ll 2mm-jlm.ll
jlm-print --j2rx --file 2mm-opt.ll

throws the follwing

terminate called after throwing an instance of 'jlm::error'
  what():  expected at least two arguments.
