* remove SkTCastGravatar Mike Klein2018-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | SkTCast is functionally equivalent to reinterpret_cast. The comment about SkTCast helping to avoid strict alising issues is not true. Dereferencing a pointer cast to a pointer of an unrelated type is always undefined, even if smuggled through a union like in SkTCast. To really avoid aliasing issues, you need to make a union[1] of the two value types, or better, memcpy between values. I've had to fix MatrixText.cpp where switching to reinterpret_cast actually let Clang notice and warn that we're exploiting undefined behavior, and GrSwizzle.h and SkCamera.cpp caught by GCC. I've switched SkTLList over to use SkAlignedSTStorage, which seems to help convince some GCC versions that fObj is used in a sound way. [1] The union punning trick is non-standard in C++, but GCC and MSVC both explicitly support it. I believe Clang does not officially explicitly support it, but probably does quietly for GCC compatibility.

* *SkTCast<int*>(float*) -> memcpyGravatar Mike Klein2016-09-29
| | | | | | | | | | | | | | | In some build configurations (I think, GN, GCC 6, Debug) I get a warning that i is used unintialized. This likely has something to do with GCC correctly seeing that the SkTCast construction there is illegal aliasing, and perhaps thus "doesn't happen". Might be that if the SkTCast gets inlined, it decides its implementation is secretly kosher, and so Release builds don't see this. None of this happens with the GCCs we have on the bots... too old? Instead use memcpy() here, which is well defined to do what we intended.

* Clean up SkFloatBitsGravatar mtklein2016-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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

* Implement a benchmark for GrResourceCacheGravatar commit-bot@chromium.org2013-11-21
| | | | | | | | | | | | | | | | | | | | | | | Adds "grresourcecache_add" and "grresourcecache_find" bench tests to test GrResourceCache::add and GrResourceCache::find. The tests work only with GPU backends, since GrResourceCache needs an GrGpu. Modifies bench tests to override SkBenchmark::isSuitableFor(Backend) function that specifies what kind of backend the test is inteded for. This replaces the previous "fIsRendering" flag that would indicate test that did no rendering. Adds SkCanvas::getGrContext() call to get the GrContext that the canvas ends up drawing to. The member function solves a common use-case that is also used in the benchmark added here.
