2015-06-26Revert "Revert "ART: Implement try/catch blocks in Builder""David Brazdil
This patch enables the GraphBuilder to generate blocks and edges which represent the exceptional control flow when try/catch blocks are present in the code. Actual compilation is still delegated to Quick and Baseline ignores the additional code. To represent the relationship between try and catch blocks, Builder splits the edges which enter/exit a try block and links the newly created blocks to the corresponding exception handlers. This layout will later enable the SsaBuilder to correctly infer the dominators of the catch blocks and to produce the appropriate reverse post ordering. It will not, however, allow for building the complete SSA form of the catch blocks and consequently optimizing such blocks. To this end, a new TryBoundary control-flow instruction is introduced. Codegen treats it the same as a Goto but it allows for additional successors (the handlers). This reverts commit 3e18738bd338e9f8363b26bc895f38c0ec682824.

2015-06-03Improve the performance of long-to-double conversions on ARM.Roland Levillain
Use a VMLA instruction instead of VADD & VMUL instructions in long-to-double conversions on ARM. This change reduces code size and improves execution times (but does not alter precision). It trades one temporary FPU register for two temporary core registers. Change-Id: I1dc35bef6c12be8f305e5b46da98c2421686b60d

2015-05-26ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko
Avoid undefined behavior for arm64 stemming from 1u << 32 in loops with upper bound kNumberOfXRegisters. Create iterators for enumerating bits in an integer either from high to low or from low to high and use them for <arch>Context::FillCalleeSaves() on all architectures. Refactor runtime/utils.{h,cc} by moving all bit-fiddling functions to runtime/base/bit_utils.{h,cc} (together with the new bit iterators) and all time-related functions to runtime/base/time_utils.{h,cc}. Improve test coverage and fix some corner cases for the bit-fiddling functions. Bug: 13925192 Change-Id: I704884dab15b41ecf7a1c47d397ab1c3fc7ee0f7

This patch also includes: 1. Add java test for div/rem negative constants. 2. Fix a thumb2 encoding issue where the last operand is "reg, shift #amount" in some instructions. 3. Support a simple filter in arm32 assembler test to filter out unsupported cases, such as "smull r0, r0, r1, r2". 4. Add smull arm32 assembler test. 5. Add smull/umull thumb2 test. 6.
