Bug ID: 154964
Summary: Slow JSC stress tests fail on 32 bit debug bots
Classification: Unclassified
Product: WebKit
Version: Other
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Critical
Priority: P1
Component: New Bugs
Assignee: webkit-unassigned at lists.webkit.org

http://trac.webkit.org/changeset/197442 disabled FTL JIT testing
on 32 bit bots, because there is no FTL JIT on any 32 bit platforms.
But 25-35 tests started to fail on these bots:
- https://build.webkit.org/builders/Apple%20El%20Capitan%2032-bit%20JSC%20%28BuildAndTest%29/builds/1658
- https://build.webkit.org/builders/Apple%20Yosemite%2032-bit%20JSC%20%28BuildAndTest%29
The problem is that these tests seems to be very slow in debug mode,
but they didn't fail previously because jsc-stress-tests script
duplicated the timeout in case of FTL JIT is enabled:
if $enableFTL and ENV["JSCTEST_timeout"]
# Currently, using the FTL is a performance regression particularly in real
# (i.e. non-loopy) benchmarks. Account for this in the timeout.
ENV["JSCTEST_timeout"] = (ENV["JSCTEST_timeout"].to_i * 2).to_s
end
It seems we should duplicate timeout in debug mode too.
