and svg/transforms/transform-origin-css-property.xhtml reftest fails, but I can't find results on the bot.

Comment 2 Csaba Osztrogonác 2012-06-12 04:10:53 PDT

I updated expected files to make these tests pass on 64 bit:
http://trac.webkit.org/changeset/120056

And I unskipped transforms/transform-origin-css-property.xhtml, because it passes now. And I removed its Qt specific expected results, because is is a reftest.

Comment 3 Zoltan Herczeg 2012-06-13 05:17:33 PDT

Again, a libc based error.

Example: svg/W3C-SVG-1.1/paths-data-03-f.svg
The input is a large arc: "A 50 50 0 1 0 345 30"
Converted to a bezier curve by SVGPathParser::decomposeArcToCubic

Full of sinf, cosf, tanf, atan2f, so the libm implementation is critical.
