* Make SkFixedRound/Ceil/FloorToFixed as inline funcGravatar liyuqian2016-10-20
| | | | | | | | | | | | | The macros that we were using will return unsigned int32 instead of signed int32 because of the last 0xFFFF0000 mask. That may bring problems if we right shift that result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - remove dead code - rewrite float -> int converters The strategy for the new converters is: - convert input to double - floor/ceil/round in double space - pin that double to [SK_MinS32, SK_MaxS32] - truncate that double to int32_t This simpler strategy does not work: - floor/ceil/round in float space - pin that float to [SK_MinS32, SK_MaxS32] - truncate that float to int32_t SK_MinS32 and SK_MaxS32 are not representable as floats: they round to the nearest float, ±2^31, which makes the pin insufficient for floats near SK_MinS32 (-2^31+1) or SK_MaxS32 (+2^31-1). float only has 24 bits of precision, and we need 31. double can represent all integers up to 50-something bits. An alternative is to pin in float to ±2147483520, the last exactly representable float before SK_MaxS32 (127 too small). Our tests test that we round as floor(x+0.5), which can return different numbers than round(x) for negative x. So this CL explicitly uses floor(x+0.5). I've updated the tests with ±inf and ±NaN, and tried to make them a little clearer, especially using SK_MinS32 instead of -SK_MaxS32. I have not timed anything here. I have never seen any of these methods in a profile. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2012333003 Review-Url: https://codereview.chromium.org/2012333003

| | | | | | | | | | | | | | | | | | | | unused headers and fixes a couple of bugs exposed by changing the random number generator: First, the function SkMatrix::getMaxStretch() had an error where it was testing the square of a number against near-zero. This led to it occasionally taking a cheaper but imprecise path for computing the eigenvalues of the matrix. It's been replaced with a check against the square of SK_ScalarNearlyZero. The second case was a failure in ClipStackTest, where it hit the rare case of a practically empty clip stack (it has a single Union) and we set a tight bounds. The bounds rect doesn't get set by GrReducedClip::ReduceClipStack() in this case, so when it clips the reduced stack it's clipping against garbage, and the resulting regions don't match. The solution is to initialize the tightBounds rect. git-svn-id: http://skia.googlecode.com/svn/trunk@7952 2bbb7eff-a529-9590-31e7-b0007b416f81
* eliminate all warnings in non-thirdparty code on macGravatar humper@google.com2013-01-07
| | | | | | | | | | | | | | | | Most of these issues were due to functions whose definitions appear in header files; I changed those functions to be 'static inline' instead of just 'static' or 'inline', which kills the warning for such functions. Other functions that were static or anonymous-namespaced but were unused in cpp files were probably called at some point but are no longer; someone who knows more than I do should probably scrub all the functions I either deleted or #if 0'ed out and make sure that the right thing is happening here. Lots of unused variables removed, and one nasty const issue handled. There remains a single warning in thirdparty/externals/cityhash/src/city.cc on line 146 related to a signed/unsigned mismatch. I don't know if we have control over this library so I didn't fix this one, but perhaps someone could do something about that one.

* fix warnings on Mac in testsGravatar caryclark@google.com2012-06-06
| | | | | | | | | | | | | | | | | | Fix these class of warnings: - unused functions - unused locals - sign mismatch - missing function prototypes - missing newline at end of file - 64 to 32 bit truncation The changes prefer to link in dead code in the debug build with 'if (false)' than to comment it out, but trivial cases are commented out or sometimes deleted if it appears to be a copy/paste error.
