2052865 - [riscv64] Failure in test wasm/binop-divrem-with-constant-riscv64-ion-codegen.js

Status: RESOLVED DUPLICATE of bug 2051600

(Core :: JavaScript Engine: JIT, defect)

Description

[Rong Bao [:csmantle]]

The following tests are failing on both riscv64-simulator and native riscv64:

    --wasm-compiler=optimizing wasm/binop-divrem-with-constant-riscv64-ion-codegen.js
    --setpref=wasm_test_serialization=true wasm/binop-divrem-with-constant-riscv64-ion-codegen.js
    --wasm-compiler=optimizing --no-avx wasm/binop-divrem-with-constant-riscv64-ion-codegen.js

One sample output is as follows.

This is possibly due to the recent Bug 2050735, where this test was first added.

The following mozconfig is used for riscv64-simulator:

mk_add_options AUTOCLOBBER=1
ac_add_options --with-ccache=sccache
ac_add_options --enable-project=js
ac_add_options --enable-debug
ac_add_options --enable-debug-symbols
ac_add_options --enable-optimize
ac_add_options --enable-jit
ac_add_options --enable-wasm-jspi
ac_add_options --enable-simulator=riscv64
ac_add_options --enable-linker=mold
