Hi everyone The following behavior (in R 3.6.1 and R-devel r77040) caught me by surprise today: truthy <- c(TRUE, FALSE) falsy <- c(FALSE, TRUE, FALSE) if (truthy) "check" #> Warning in if (truthy) "check": the condition has length > 1 and only the #> first element will be used #> [1] "check" if (falsy) "check" #> Warning in if

I have access to a cluster on which I have been supplied with R 3.1.0 which appears to have been built using the intel compiler tools. The following minimal Fortran file: subroutine truth(lind) logical lind lind = .TRUE. end Compiles thusly: arcadia> R CMD SHLIB truth.f ifort -fpic -O3 -xHOST -axCORE-AVX-I -fp-model precise -c truth.f -o truth.o ifort: command

Hi all, During discussions about assertions in the Flang project, we noticed that there are a lot of cases in LLVM that #ifndef NDEBUG is used as a guard for non-assert code that we want enabled in debug builds. This works fine on its own, however it affects the behaviour of LLVM_ENABLE_ASSERTIONS; since NDEBUG controls whether assertions are enabled or not, a lot of debug code gets enabled in

Hi I have a scatterplot of points with pch=1 and a single point with pch=3, lwd=3. It has a high line width to attract attention to it. The following script plot(rnorm(10),rnorm(10),col="black") points(rnorm(10),rnorm(10),col="red") points(0,0,pch=3,lwd=3) if(TRUE){ legend("bottomleft",c("a","b","Truth"),pch=c(1,1,3),col=c

...uot;bool" in there seems a bit redundant. I think there's three kinds values involved in the predicates. The first is the inputs like these values come from other parts of the match and it makes sense that they belong in 'ins'. The second is values that are directly related to the truthiness of the predicate such as bool, unsigned (register number), MachineInstr*, etc.. These are the result of the underlying function and there can only be one of these per predicate. The type can potentially be std::pair or std::tuple to give multiple results provided a suitable conversion to bool i...

...hat fills out the PreferredTuple (passed by reference) whenever it returns true for a successful match. We could have made the predicate return std::pair<bool, PreferredTuple> instead but that's less efficient (it would be an sret return on many targets) and would require us to define the truthiness (no examples of are in this email as I expect it to be a rare thing to need) in order to act as a predicate. Normally, you'd feed this into a (create_imm ...) or a (create_operand ...) in the apply section. However, in this particular case the data being passed determines the entirety of th...
