The summary stats for the xin and yin variables below are correct. However, if I use plot(xin,yin), an exception is thrown saying that "object xin is not found." Also, it is apparent that I can't successfully replace the x and y vectors with values from xin and yin. The four plots on one panel are showing but the r...

Hi Yin, I second David's words. I use shared libs myself on debug builds, but static builds with gold on a local disk is pretty feasible. Before I used gold, I had to have 16GB of RAM on my laptop, now I need less than 8GB for static builds. On 28 January 2016 at 23:58, Yin Ma via cfe-dev <cfe-d...

Hi Duncan, Yes, exactly. However, we need define Opcode MIN/MAX Into ISDOpcodes.h. Do you like to add those two definitions Into the tree?

Hi Duncan, To use select, usually, there is a compare before select. Presence of comparison will disable some opportunities to optimize some code. Select and Compare is not associative neither.

...changes the behavior of a program. So we need remove the case if (isa<ConstantPointerNull>(Callee) at InstCombineCalls.cpp:918 and treat calling Null pointer reachable. How do you think? Is there any reason that we should convert a calling null pointer to a store? Thanks, Yin -------------- next part -------------- An HTML attachment was scrubbed...

...wondering whether the llvm-mca support the assembly code for the ARM? I cross-compile the test file for ARM like that: clang test.c -O2 -target arm-linux-gnueabihf -static -S -o test.s If I want to check the performance using llvm-mca, is there any option of "-mcpu" for ARM ?

..., I assume you have a powerful machine. Our drive space is on network mounted machined by IT department. The machine is default Ubuntu setup with 8 cores. Shared build is showing huge advantage due to size reduction. I will try those two debug options to see how it works.
