[LLVMdev] Is ConstantFoldConstantExpression meant to be idempotent?
I noticed a change in LLVM's behavior between 3.2 and 3.3/ToT, but I'm not sure if it qualifies as a bug/regression or not. The change is that in 3.3 and tip of trunk, calling ConstantFoldConstantExpression on i64 and (i64 add (i64 add (i64 ptrtoint (i64* getelementptr (i64* null, i32 1) to i64), i64 ptrtoint (i64* getelementptr (i64* null, i32 1) to i64)), i64 15), i64 -16)

...A, so it should not have any > further knowledge about the rest of the environment. What does RTLinux on an R-class CPU present itself as? My guess would be "armv7l" too. I'm not too concerned about deciding that we only care about A-class Linux, but I am concerned about taking an unprincipled approach to the l/b suffix. Not enough that I can't live with it though. As you say this whole area's enough of a mess already, one more bit isn't going to break the world. Cheers. Tim.

Using functions/loops for repetitive commands
I still need to do some repetitive statistical analysis on some outcomes from a dataset. Take the following as an example; id sex hiv age famsize bmi resprate 1 M Pos 23 2 16 15 2 F Neg 24 5 18 14 3 F Pos 56 14 23 24 4 F Pos 67 3 33 31 5 M Neg 34 2 21 23 I want to know if there are statistically detectable differences in all of the continuous variables in
