Godbolt-like for vim

A simple vim plugin that binds \gb to open a split with the assembly of the current source file. If the first line of the file starts with // godbolt: the rest of the line will be appended to the list of arguments. You can see an example here:

This also works for Swift:

The following variables can be used to modify the behavior (the defaults are shown):

# define the compiler you want to use
let g:godbolt_swiftc = 'swiftc'
let g:godbolt_clang = 'clang'

# define some extra args to include
let g:godbolt_cpp_args = "-std=c++20"
let g:godbolt_c_args = "-std=c17"
let g:godbolt_swift_args = ""

Todo?:

• Read from a compile_commands.json file.
• Add a different command for -Xclang -fsyntax-only -Xclang -ast-dump
• Add a different command for -emit-llvm
• Add a different command to run -flto
• Parse away some of the cfi statements.
