Hi all, in r152019 (from ctopper), the number of available registers of any type in a machine description is decreased to 256 because it needs to be encoded in uint8_t now. I'm trying to support an experimental embedded architecture with more registers (out of tree), but now that becomes impossible. Anyone knows a solution? Thanks, Bjorn De Sutter Computer Systems Lab Ghent University

Hi Sergei, thanks for considering my question. We if-convert some code, such that the basic block looks as follows after if-conversion: ld char from A into R1 p1 = R1>255? (generate the predicate) p1 | R1 = 255 (conditional execution) st char R1 to A ld char from A+1 into R2 p2 = R2>255? (generate the predicate) p2 | R2 = 255 (conditional execution) store char R2 to A+1 The problem is

In ScheduleDagInstr.cpp, a todo is mentioned to make this pass use real alias analysis information. Is anybody working on this already? I am working on a VLIW-like backend and have If-conversion working rather well, but the problem is that independent loads and stores in the if-converted blocks are not scheduled well at all. Thanks, prof. Bjorn De Sutter Computer Systems Lab Ghent University

We observed exact same problem, and I did put in place a mechanism to recognize and break such false dependencies right before pre-RA scheduler (in DAG->DAG lowering), but the immediate observed effect for our back end was performance reduction, since none of the current schedulers were capable of dealing with newly presented parallelism in BB (resulted in high reg pressure and

I changed it to uint16_t in r152100. Is that enough for your architecture?

I am working on something very(very) similar, what is the exact nature of your question?

Hi, that solved my problem on trunk as well, thanks. Strange that you have to include this though.

Murray, Your commits earlier this evening to zh_CN.GB18030 fixed that -STABLE breakage, but zh_CN.GBK appears still to be missing, which causes 'make installworld' to fail. Can you please fix this as well? install -m 644 -o root -g wheel uk_UA.KOI8-U.out /usr/share/locale/uk_UA.KOI8-U/LC_CTYPE install -m 644 -o root -g wheel zh_CN.eucCN.out /usr/share/locale/zh_CN.eucCN/LC_CTYPE

Hi all, I am working on a CGRA backend (something like a 2D VLIW), and we also absolutely need predication. I extended the IfConversion pass to allow it to be executed multiple times and to predicate already predicated code. This is necessary to predicate code with nested conditional statements. At this point, we support or, and, and conditional predicates (see Scott Mahlke's papers on this

Can you try making the constructor "explicit" for PrintReg in include/llvm/Target/TargetRegisterInfo.h. I think you were getting an implicit conversion there which should probably be fixed anyway.

Hi Craig, I updated from the trunk some minutes ago, and thus got the "explicit". PrintReg constructor. When I do not include raw_ostream.h after including Debug.h in the backend cpp files, I now get compilation errors, not only when trying to print floats but also in other places. For example, for the code bool ADRESRegisterInfo::hasReservedCallFrame(const MachineFunction &MF)
