From 0486fb4de505b8116a0034bdde4918cd783325b9 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Thu, 1 Jul 2021 09:31:48 -0500 Subject: [PATCH] Finish implementing the extended name section proposal (#298) * begin implementing extended name section * add element and data names * Remove extended name feature * Print out names in the custom name maps This commit updates wasmprinter to consult the name section for not only function/local names but all the other names which are now parsed in the name section as well. * Implement the extended name section proposal in `wast` * Print labels for blocks as well This recognizes labels in the custom name section when printing wasm modules and attempts to print the labels. This doesn't yet print the symbolic name on the `br` or related instructions, but it at least prints the name on the label instruction itself. * Fix a test with custom section orderings * Remove a stray feature Co-authored-by: Sam Sartor --- crates/dump/src/lib.rs | 82 ++-- crates/wasmparser/src/binary_reader.rs | 7 + crates/wasmparser/src/primitives.rs | 7 + crates/wasmparser/src/readers/name_section.rs | 66 ++- crates/wasmprinter/src/lib.rs | 458 ++++++++++++------ crates/wast/src/ast/expr.rs | 2 + crates/wast/src/ast/global.rs | 4 + crates/wast/src/ast/instance.rs | 4 + crates/wast/src/ast/memory.rs | 9 + crates/wast/src/ast/table.rs | 8 + crates/wast/src/ast/tag.rs | 4 + crates/wast/src/ast/types.rs | 10 +- crates/wast/src/binary.rs | 234 ++++++--- .../src/resolve/deinline_import_export.rs | 2 + crates/wast/src/resolve/types.rs | 1 + crates/wast/tests/annotations.rs | 6 +- fuzz/fuzz_targets/roundtrip.rs | 6 +- tests/dump/bundled.wat.dump | 8 + tests/dump/instance-expand.wat.dump | 6 + tests/dump/instance-type2.wat.dump | 6 + tests/dump/instantiate.wat.dump | 13 +- tests/dump/module-types.wat.dump | 7 + tests/dump/try-delegate.wat.dump | 8 + tests/roundtrip.rs | 16 +- 24 files changed, 715 insertions(+), 259 deletions(-) diff --git a/crates/dump/src/lib.rs b/crates/dump/src/lib.rs index 1acfd6c36d..d741c3ad3c 100644 --- a/crates/dump/src/lib.rs +++ b/crates/dump/src/lib.rs @@ -321,6 +321,49 @@ impl<'a> Dump<'a> { Ok(()) } + fn print_name_map(&mut self, thing: &str, n: NameMap<'_>) -> Result<()> { + write!(self.state, "{} names", thing)?;
