[llvm-dev] Help: Windows: lli crashes on 32 arch but not on 64 arch

Hello LLVM list

I am running with lli,  a simple HelloWorld program twice, once targeted 
to 32 bits arch, the other targeted to 64 bit arch. While it is working 
fine with the 64 arch, it craches with the 32 arch. Below are the steps


clang.cmd -v -g -m64 -emit-llvm -S hw.c -o hw-m64.ll


clang.cmd -v -g -m32 -emit-llvm -S hw.c -o hw-m32.ll

What is the best way to debug the 32 bit arch lli.exe under VS2019?


D:\projects\clang>type hw.c
#include <stdio.h>
int main() {
         printf("Hello World!\n");
         return 0;
}

[llvm-dev] Help: Windows: lli crashes on 32 arch but not on 64 arch

Try setting the target triple for lli to `i686-pc-windows-elf`. The COFF
backend for MCJIT is not complete, but ELF typically works
