Bug 124550 – run-jsc-stress-tests only supports host environments that have make installed

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Mark Hahnenberg]

This might not be the case for all hosts, so we should write an alternate "backend" for run-jsc-stress-tests to use normal shell commands rather than Makefiles. This will probably sacrifice the ability to run tests in parallel, at least in the first version.

[Mark Hahnenberg]

This new backend could be enabled by passing --shell-runner to run-jsc-stress-tests. There would also be a (default) flag for --make-runner.
