Compile Commands

My preferred compile commands to quickly look up

Programming languages

C - gcc -std=gnu99 -Werror -Wfatal-errors -Wall -Wpedantic blub.c -o blub
- if necessary, remove -Wpedantic, since it warns for features definitely included by using gnu99 as compiler
- gcc -c -std=gnu99 -Werror -Wfatal-errors -Wall -Wpedantic blub.c -o blub the -c to get object file only instead of binary
C++ -
- g++ -pedantic -Wall -Wextra -Werror -c blob.cpp blub.cpp -> object files
- g++ -Wall -o blub blob.o blub.o -> binaries
- blob.cpp gets linked (blub.cpp would likely start with something like #include "blob.h")
Assembly - (this is called assembling instead of compiling) gcc -c blub.s
- on systems that aren't ARM:
  1. aarch64-linux-gnu-gcc -c blub_asm.s
  2. aarch64-linux-gnu-gcc -c blub_c.c
  3. aarch64-linux-gnu-g++-10 -c blub.cpp
  4. linking: aarch64-linux-gnu-g++-10 -o blub blob.o blub_asm.o blub_c.o
  5. running: qemu-aarch64 ./blub
- assembling and disassembling single commands:
  - echo "adds x0, x0, #5" | llvm-mc -triple=aarch64 --show-encoding
  - echo "0x00 0x14 0x00 0xb1" | llvm-mc -triple=aarch64 -disassemble --show-encoding
System Verilog - iverilog -Wall -g2012 1.sv 2.sv 3_tb.sv 3.sv -o 3_tb <- tb for testbench simulation
