2018-03-06scons: Switch from the print statement to the print function.Gabe Black
Starting with version 3, scons imposes using the print function instead of the print statement in code it processes. To get things building again, this change moves all python code within gem5 to use the function version. Another change by another author separately made this same change to the site_tools and site_init.py files.

2016-10-26hsail,gpu-compute: fixes to appease clang++Tony Gutierrez
fixes to appease clang++. tested on: Ubuntu clang version 3.5.0-4ubuntu2~trusty2 (tags/RELEASE_350/final) (based on LLVM 3.5.0) Ubuntu clang version 3.6.0-2ubuntu1~trusty1 (tags/RELEASE_360/final) (based on LLVM 3.6.0) the fixes address the following five issues: 1) the exec continuations in gpu_static_inst.hh were marked as protected when they should be public. here we mark them as public 2) the Abs instruction uses std::abs() in its execute method. because Abs is templated, it can also operate on U32 and U64, types, which cause Abs::execute() to pass uint32_t and uint64_t types to std::abs() respectively. this triggers a warning because std::abs() has no effect in this case. to rememdy this we add template specialization for the execute() method of Abs when its template paramter is U32 or U64. 3) Some potocols that utilize the code in cprintf.hh were missing includes to BoolVec.hh, which defines operator<< for the BoolVec type. This would cause issues when the generated code would try to pass a BoolVec type to a method in cprintf.hh that used operator<< on an instance of a BoolVec. 4) Surprise, clang doesn't like it when you clobber all the bits in a newly allocated object. I.e., this code: tlb = new GpuTlbEntry\[size\]; std::memset(tlb, 0, sizeof(GpuTlbEntry) \* size); Let's use std::vector to track the TLB entries in the GpuTlb now... 5) There were a few variables used only in DPRINTFs, so we mark them with M5_VAR_USED.

2016-06-09gpu-compute: parametrize Wavefront sizejkalamat
Eliminate the VSZ constant that defined the Wavefront size (in numbers of work items); replaced it with a parameter in the GPU.py configuration script. Changed all data structures dependent on the Wavefront size to be dynamically sized. Legal values of Wavefront size are 16, 32, 64 for now and checked at initialization time.
2016-02-06style: eliminate explicit boolean comparisonsSteve Reinhardt
Result of running 'hg m5style --skip-all --fix-control -a' to get rid of '== true' comparisons, plus trivial manual edits to get rid of '== false'/'== False' comparisons. Left a couple of explicit comparisons in where they didn't seem unreasonable: invalid boolean comparison in src/arch/mips/interrupts.cc:155 >> DPRINTF(Interrupt, "Interrupts OnCpuTimerINterrupt(tc) == true\n");<< invalid boolean comparison in src/unittest/unittest.hh:110 >> "EXPECT_FALSE(" #expr ")", (expr) == false)<<
