2016-03-21gpu-compute: remove unused variable from scoreboard check stagejkalamat
appease clang by removing the unused private member variable, 'numGlbMemPipes', from the scoreboard check stage
2016-03-17syscall_emul: move mmapGrowsDown() to LiveProcessSteve Reinhardt
The mmapGrowsDown() method was a static method on the OperatingSystem class (and derived classes), which worked OK for the templated syscall emulation methods, but made it hard to access elsewhere. This patch moves the method to be a virtual function on the LiveProcess method, where it can be overridden for specific platforms (for now, Alpha). This patch also changes the value of mmapGrowsDown() from being false by default and true only on X86Linux32 to being true by default and false only on Alpha, which seems closer to reality (though in reality most people use ASLR and this doesn't really matter anymore). In the process, also got rid of the unused mmap_start field on LiveProcess and OperatingSystem mmapGrowsUp variable.

Match changes in output stream.
2016-02-18gpu: fix bugs with MemFence, Flat Instrs and Resource utilizationJohn Kalamatianos
Both Memory Fence is now flagged as Global Memory only to avoid resource oversubscribing. Flat instructions now check for Shared Memory resource busy to avoid oversubscribing resources. All WaitClass resources now use cycles (not ticks) to register the number of pipe stages between Scoreboard and Execute to be consistent with instruction scheduling logic which always used clock cycles.
2016-02-17gpu-compute: remove brig_object.hh from hsa_object.ccTony Gutierrez
brig_object.hh is specific to the HSAIL ISA, and hence should not be included in ISA-agnostic code.
