History

shua a98acff0b9 gen-dev: impl Num.neg for Dec,F32,F64 Dec negation was implemented across gen-dev, gen-llvm, gen-wasm as a call to the compiled zig function `bitcode::DEC_NEGATE`. f32 and f64 negation were implemented already for gen-llvm, gen-wasm. for gen-dev x86_64, float negation is implemented by flipping the sign bit, which means `xorps` for f32, and `xorpd` for f64 for gen-dev aarch64, there is conveniently a `fneg` instruction		2024-11-23 19:17:55 +01:00

Running our CodeGen tests

Our code generation tests are all in this crate. Feature flags are used to run the tests with a specific backend. For convenience, some aliases are added in .cargo/config:

[alias]
test-gen-llvm = "test -p test_gen"
test-gen-dev = "test -p test_gen --no-default-features --features gen-dev"
test-gen-wasm = "test -p test_gen --no-default-features --features gen-wasm"

So we can run:

cargo test-gen-llvm

To run the gen tests with the LLVM backend. To filter tests, append a filter like so:

> cargo test-gen-wasm wasm_str::small
    Finished test [unoptimized + debuginfo] target(s) in 0.13s
     Running src/tests.rs (target/debug/deps/test_gen-b4ad63a9dd50f050)
