[RFC] Turn the MachineOutliner on by default in AArch64 under -Oz
Sorry, I was using a modified compiler, which by coincidence made the
bug much easier to reproduce.
In some rare cases, the compiler will use x30 as a general-purpose
register; in that case, outlining breaks because the "ret" branches to
the wrong address. Testcase (reproduce with "clang -O3

Hi R community,
I am trying to fit a PLS model with response Y and predictor X, where X consists of at least 30 columns (say x1, x2, ..., x30). Aside from studying the relationship of Y and x1, ..., x30, I am also interested in studying the effect of quadratic terms (x1^2, ..., x30^2) and two-way interactions (x1*x2, x1*x3, ..., x29*x30) on Y.
My R code is
dat.pls<-plsr(Y ~ X^2 + I(X^2), ncomp = 2, method="oscorespls")...

[RFC] Turn the MachineOutliner on by default in AArch64 under -Oz
Thanks for reducing that for me!
The outliner pulls out the following:
OUTLINED_FUNCTION_0: // @OUTLINED_FUNCTION_0
.cfi_sections .debug_frame
.cfi_startproc
// %bb.0:
adrp x29, g1
add x29, x29, :lo12:g1
adrp x30, g2 // This adrp shouldn’t have been outlined.
ret
It shouldn’t be pulling out that adrp. There’s a special case for arps in the outliner which hinged on the assumption that x30 wouldn’t be used in that way. I just finished writing a fix which I’ll have up short...

aspect ratio ?
Can someone enlighten me on what the status is of aspect ratio in theora
is ?
The ti structure has aspect_num and _den values, which I assume give the
intended display aspect ratio (e.g. 4/3).
The sample files on the bittorrent seem to say both values are 0 for all
files. I'd think it should at least be made impossible to have a 0 as
the denominator.
