//! Tests for the C ABI.
//! Those tests are passing back and forth struct and values across C ABI
//! by combining Zig code here and its mirror in cfunc.c
//! To run all the tests on the tier 1 architecture you can use:
//! zig build test-c-abi -fqemu
//! To run the tests on a specific architecture:
//! zig test -lc main.zig cfuncs.c -target mips-linux --test-cmd qemu-mips --test-cmd-bin
