Comment #4 on issue 3259 by [email protected]: Floor of div on ARM
returns incorrect results.
http://code.google.com/p/v8/issues/detail?id=3259
This does not seem to be fixed. When I enabled concurrent OSR, it happened
again.
out/arm.release/d8 --test --random-seed=715522483 --stress-opt --always-opt
--nohard-abort --nodead-code-elimination --allow-natives-syntax
--nouse_inlining --noenable_sudiv test/mjsunit/mjsunit.js
test/mjsunit/math-floor-of-div-nosudiv.js --always-osr --noconcurrent-osr
Note that concurrent OSR is off, but --always-OSR is specified.
We get
============ Stress 1/5 ============
test/mjsunit/mjsunit.js:178: Failure: expected <-50> found <0>
throw new MjsUnitAssertionError(message);
^
Error
at new MjsUnitAssertionError (test/mjsunit/mjsunit.js:31:16)
at fail (test/mjsunit/mjsunit.js:178:11)
at assertEquals (test/mjsunit/mjsunit.js:249:7)
at test_div (test/mjsunit/math-floor-of-div-nosudiv.js:55:49)
at test/mjsunit/math-floor-of-div-nosudiv.js:183:1
Same thing happens with --enable_sudiv.
I'll mark the tests as PASS/FAIL for now, since this really has not really
anything to do with concurrent OSR, which would be blocked by these two
tests.
