llvm-as:tldr:5a295
This command is a combination of two commands piped together, cat
and llvm-as
, used to compile LLVM intermediate representation (IR) code.
Here's the breakdown:
-
cat ${path-to-source-ll}
: Thecat
command is used to read the contents of a file and display it to the console.${path-to-source-ll}
is a placeholder for the actual path to the LLVM IR source file that you want to compile. This command reads the content of the source file and outputs it to the console. -
|
: The vertical bar symbol|
is the pipe operator, which redirects the output from the previous command to the input of the next command. -
llvm-as -o ${path-to-out-bc}
: Thellvm-as
command is used to assemble LLVM IR code into a LLVM bitcode.${path-to-out-bc}
is a placeholder for the actual path where you want to save the resulting LLVM bitcode file. This command takes the input from the previouscat
command (the contents of the source file) and assembles it into a LLVM bitcode file, which is then saved to the specified path.
To summarize, this command reads the contents of a LLVM IR source file using cat
, then assembles it into a LLVM bitcode file using llvm-as
, and finally saves the resulting bitcode file to the given output path.
