* ART: Optimizing compiler intrinsicsAndreas Gampe2015-01-1522-75/+1873
| | | | | | | | | Add intrinsics infrastructure to the optimizing compiler. Add almost all intrinsics supported by Quick to the x86-64 backend. Further intrinsics require more assembler support. Change-Id: I48de9b44c82886bb298d16e74e12a9506b8e8807

| * [optimizing compiler] Compute live spill sizeMark Mendell2015-01-158-15/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current stack frame calculation assumes that each live register to be saved/restored has the word size of the machine. This fails for X86, where a double in an XMM register takes up 8 bytes. Change the calculation to keep track of the number of core registers and number of fp registers to handle this distinction. This is slightly pessimal, as the registers may not be active at the same time, but the only way to handle this would be to allocate both classes of registers simultaneously, or remember all the active intervals, matching them up and compute the size of each safepoint interval.

| * | ART: dex2oat flag for HGraphVisualizer dump fileDavid Brazdil2015-01-135-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new '--dump-cfg=<file>' flag to dex2oat which specifies the file that HGraphVisualizer will store its output into. Until now the graph was dumped to 'art.cfg' in the current working directory. To make Checker work with run-test, the output directory needs to be customizable.

Change the 'hidden' argument register from XMM0 to XMM7 to avoid a conflict. This change was requested to simplify the Optimizing compiler implementation.

* | Fix handling of long argument spanning register/memory.Nicolas Geoffray2015-01-124-47/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Comment in arm_lir.h says: * If a 64-bit argument would span the register/memory argument * boundary, it will instead be fully passed in the frame. This change implements such logic for all platforms. We still need to pass the low part in register as well because I haven't ported the jni compilers (x86 and mips) to it. Once the jni compilers are updated, we can remove the register assignment. Note that this greatly simplifies optimizing's register allocator by not having to understand a long spanning register and memory. Change-Id: I59706ca5d47269fc46e5489ac99bd6576e87e7f3

| |/ | | | | | | | | | | | | | | | | | | | | | | 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.
