Hi All,

Facing below error during compilation of chrome on platform similar to linux

[  176s] [12/20] ACTION //v8:run_mksnapshot_default(//tizen_src/build/toolchain/tizen:tizen_clang_arm)
[  176s] FAILED: gen/v8/embedded.S snapshot_blob.bin
[  176s] python3 ../v8/tools/run.py ./mksnapshot --turbo_instruction_scheduling --stress-turbo-late-spilling --target_os=linux --target_arch=arm --embedded_src gen/v8/embedded.S --predictable --no-use-ic --embedded_variant Default --random-seed 314159265 --startup_blob snapshot_blob.bin --no-native-code-counters
[  176s] qemu: uncaught target signal 4 (Illegal instruction) - core dumped

Any input related to above error or any clue how to debug further will be of great help

Thanks in Advance

Uzair

Whats version and what build args are you using.

In particular are you turning off the shared compression cage?
