Hi, I followed the instructions for building FPC with LLVM presented here [1]. Now I am interested in generating LLVM assembly from the corresponding Pascal code. Is there any method to achieve this?
Just use -al option, this will leave the generated .ll file present after compilation. You can also use -vx option to see how clang is called: Pierre muller@gcc187:~/pas/check$ fpc -al -vx hello.pp Free Pascal Compiler version 3.3.1-13440-ge4911588c5-unpushed-dirty [2023/07/26] for x86_64 Copyright (c) 1993-2023 by Florian Klaempfl and others Target OS: Linux for x86-64 Compiling hello.pp Assembling program Executing "/home/muller/bin/clang" with command line "-x ir -O0 -fno-omit-frame-pointer -static -target x86_64-unknown-linux-gnu -c -o hello.o hello.ll " Linking hello Executing "/usr/bin/ld.bfd" with command line "-b elf64-x86-64 -m elf_x86_64 --dynamic-linker=/lib64/ld-linux-x86-64.so.2 -s -L. -o hello -T link3003900.res -e _start --eh-frame-hdr" Size of Code: 336615 bytes Size of initialized data: 9568 bytes Size of initialized data: 6648 bytes Size of uninitialized data: 7016 bytes 3 lines compiled, 0.1 sec, 336615 bytes code, 23232 bytes data muller@gcc187:~/pas/check$ ls -altr hello* -rw-rw-r--. 1 muller muller 32 Aug 4 2022 hello.pp -rw-rw-r--. 1 muller muller 5220 Jul 26 11:43 hello.ll -rw-rw-r--. 1 muller muller 2584 Jul 26 11:43 hello.o -rwxrwxr-x. 1 muller muller 447584 Jul 26 11:43 hello _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
