From 924533fbcd0181f4460a13adc5762ee52f97de58 Mon Sep 17 00:00:00 2001 From: Thomas Lively Date: Mon, 13 May 2024 14:18:01 -0700 Subject: [Parser] Parse wast scripts (#6581) The spec tests use an extension of the standard text format that includes various commands and assertions used to test WebAssembly implementations. Add a utility to parse this extended WebAssembly script format and use it in wasm-shell to check that it parses our spec tests without error. Fix a few errors the new parser found in our spec tests. A future PR will rewrite wasm-shell to interpret the results of the new parser, but for now to keep the diff smaller, do not do anything with the new parser except check for errors. --- test/spec/bulk-memory.wast | 15 ++++++++------- test/spec/bulk-memory64.wast | 14 +++++++------- test/spec/elem_reftypes.wast | 1 + test/spec/multivalue.wast | 12 ++++++------ test/spec/old_select.wast | 4 ++-- test/spec/ref_cast.wast | 2 +- test/spec/typed_continuations.wast | 3 +++ 7 files changed, 28 insertions(+), 23 deletions(-) (limited to 'test/spec') diff --git a/test/spec/bulk-memory.wast b/test/spec/bulk-memory.wast index 1a2d3e440..d7919c74f 100644 --- a/test/spec/bulk-memory.wast +++ b/test/spec/bulk-memory.wast @@ -37,10 +37,10 @@ (invoke "fill" (i32.const 0x10000) (i32.const 0) (i32.const 0)) ;; Writing 0 bytes outside of memory limit is NOT allowed. -(assert_trap (invoke "fill" (i32.const 0x10001) (i32.const 0) (i32.const 0))) +(assert_trap (invoke "fill" (i32.const 0x10001) (i32.const 0) (i32.const 0)) "oob") ;; Negative size -(assert_trap (invoke "fill" (i32.const 15) (i32.const 14) (i32.const -2))) +(assert_trap (invoke "fill" (i32.const 15) (i32.const 14) (i32.const -2)) "oob") (assert_return (invoke "load8_u" (i32.const 15)) (i32.const 0)) ;; memory.copy @@ -88,7 +88,7 @@ (assert_return (invoke "load8_u" (i32.const 16)) (i32.const 0)) ;; Overlap, source < dest but size is out of bounds -(assert_trap (invoke "copy" (i32.const 13) (i32.const 11) (i32.const -1))) +(assert_trap (invoke "copy" (i32.const 13) (i32.const 11) (i32.const -1)) "oob") (assert_return (invoke "load8_u" (i32.const 10)) (i32.const 0)) (assert_return (invoke "load8_u" (i32.const 11)) (i32.const 0xaa)) (assert_return (invoke "load8_u" (i32.const 12)) (i32.const 0xbb)) @@ -106,8 +106,8 @@ (invoke "copy" (i32.const 0) (i32.const 0x10000) (i32.const 0)) ;; Copying 0 bytes outside of memory limit is NOT allowed. -(assert_trap (invoke "copy" (i32.const 0x10001) (i32.const 0) (i32.const 0))) -(assert_trap (invoke "copy" (i32.const 0) (i32.const 0x10001) (i32.const 0))) +(assert_trap (invoke "copy" (i32.const 0x10001) (i32.const 0) (i32.const 0)) "oob") +(assert_trap (invoke "copy" (i32.const 0) (i32.const 0x10001) (i32.const 0)) "oob") ;; memory.init (module @@ -143,8 +143,9 @@ (invoke "init" (i32.const 0) (i32.const 4) (i32.const 0)) ;; Writing 0 bytes outside of memory / segment limit is NOT allowed. -(assert_trap (invoke "init" (i32.const 0x10001) (i32.const 0) (i32.const 0))) -(assert_trap (invoke "init" (i32.const 0) (i32.const 5) (i32.const 0))) +(assert_trap (invoke "init" (i32.const 0x10001) (i32.const 0) (i32.const 0)) "oob") + +(assert_trap (invoke "init" (i32.const 0) (i32.const 5) (i32.const 0)) "oob") ;; OK to access 0 bytes at offset 0 in a dropped segment.
