* Implement double and float support for arm in register allocator.Nicolas Geoffray2015-01-081-5/+44
| | | | | | | | | | | | The basic approach is: - An instruction that needs two registers gets two intervals. - When allocating the low part, we also allocate the high part. - When splitting a low (or high) interval, we also split the high (or low) equivalent. - Allocation follows the (S/D register) requirement that low registers are always even and the high equivalent is low + 1.

* Ensure opt. compiler doesn't get core & FP registers mixed up.Roland Levillain2014-11-271-1/+8
| | | | | | | | Replace Location::As<T>() with two method methods (Location::AsRegister<T>() and Location::AsFpuRegister<T>()) checking the kind of the location (register). Change-Id: I22b4abee1a124b684becd2dc1caf33652b911070

* Do not update Out after it has a valid location.Nicolas Geoffray2014-11-071-1/+14
| | | | | | | | | | Slow paths use LocationSummary to know where to move things around, and they are executed at the end of the code generation. This fix is needed for https://android-review.googlesource.com/#/c/113345/. Change-Id: Id336c6409479b1de6dc839b736a7234d08a7774a

| * ART: Replace COMPILE_ASSERT with static_assert (compiler)Andreas Gampe2014-11-031-10/+10
| | | | | | | | | | | | Replace all occurrences of COMPILE_ASSERT in the compiler tree. Change-Id: Icc40a38c8bdeaaf7305ab3352a838a2cd7e7d840
* | Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-1/+3
|/ | | | | | | | | | | Fix associated errors about unused paramenters and implict sign conversions. For sign conversion this was largely in the area of enums, so add ostream operators for the effected enums and fix tools/generate-operator-out.py. Tidy arena allocation code and arena allocated data types, rather than fixing new and delete operators. Remove dead code. Change-Id: I5b433e722d2f75baacfacae4d32aef4a828bfe1b
* Fix for long parameter passed both in stack and register.Nicolas Geoffray2014-10-301-4/+9
| | | | | | | | | Fix for long parameter passed both in stack and register on 32bits architectures. The move to hard float ABI makes it so that the register index does not necessarily match the stack index anymore. Change-Id: I26b483f68ac86d336b4a37d94c38b04917668659
* Add support for static fields in optimizing compiler.Nicolas Geoffray2014-10-291-0/+9

* Support hard float on arm in optimizing compiler.Nicolas Geoffray2014-10-271-7/+31
| | | | | | Also bump oat version, needed after latest hard float switch. Change-Id: Idf5acfb36c07e74acff00edab998419a3c6b2965
* Remove the notion of dies at entry.Nicolas Geoffray2014-10-211-9/+16
| | | | | | | | | | | - Instead, explicitly say that the output does not overlap. - Inputs that must be in a fixed register do die at entry, as we know they have a location that others can not take. - There is also no need to differentiate between an input move and a connecting sibling move - those can be put in the same parallel move instruction.

| * Tidy ELF builder.Ian Rogers2014-10-091-1/+2
| | | | | | | | | | | | | | | | | | Don't do "if (ptr)". Use const. Use DISALLOW_COPY_AND_ASSIGN. Avoid public member variables. Move ValueObject to base and use in ELF builder. Tidy VectorOutputStream to not use non-const reference arguments. Change-Id: I2c727c3fc61769c3726de7cfb68b2d6eb4477e53
* | Stop converting from Location to ManagedRegister.Nicolas Geoffray2014-10-091-20/+52
|/ | | | | | | Now the source of truth is the Location object that knows which register (core, pair, fpu) it needs to refer to. Change-Id: I62401343d7479ecfb24b5ed161ec7829cda5a0b1
* Add support for floats and doubles.Nicolas Geoffray2014-10-071-16/+41
| | | | | | | - Follows Quick conventions. - Currently only works with baseline register allocator. Change-Id: Ie4b8e298f4f5e1cd82364da83e4344d4fc3621a3
* Add a prepare for register allocation pass.Nicolas Geoffray2014-10-061-0/+3
| | | | | | | | | | - Currently the pass just changes the uses of checks to the actual values. - Also optimize array access, now that inputs can be constants. - And fix another bug in the register allocator reveiled by this change. Change-Id: I43be0dbde9330ee5c8f9d678de11361292d8bd98
* Add support for inputs dying at entry of instructions.Nicolas Geoffray2014-10-061-2/+8
| | | | | | | - Start using it in places where it makes sense. - Also improve suspend check on arm to use subs directly. Change-Id: I09ac0589f5ccb9b850ee757c76dcbcf35ee8cd01
* Register allocator: refine instructions liveness.Nicolas Geoffray2014-09-271-0/+10
| | | | | | | | | Add support for instructions that die at the beginning of another instruction. Before, an instruction needed to stay alive during the instruction, so the register allocator was not able not reuse the register. Change-Id: I5f11a80b0a20778227229eb797816edcc6365297

| * Optimize suspend checks in optimizing compiler.Nicolas Geoffray2014-09-251-0/+4
| | | | | | | | | | | | | | | | | | | | - Remove the ones added during graph build (they were added for the baseline code generator). - Emit them at loop back edges after phi moves, so that the test can directly jump to the loop header. - Fix x86 and x86_64 suspend check by using cmpw instead of cmpl.

* Runtime support for the new stack maps for the opt compiler.Nicolas Geoffray2014-09-081-5/+50
| | | | | | | Now most of the methods supported by the compiler can be optimized, instead of using the baseline. Change-Id: I80ab36a34913fa4e7dd576c7bf55af63594dc1fa
