Since we are in the area, what *should* O1 do? It's basically good for nothing, since it doesn't tune for size or performance. The only good I personally ever have for it is once in a while there is a miscompile at -O1 which narrows the problem. Would it be crazy to make -O1 equivalent to -Os? - Daniel On Wednesday, September 16, 2009, Chris Lattner <clattner at apple.com>

What kinds of errors are you getting?

Hi, I recently downloaded and installed the libcpu package (from http://libcpu.org ) that uses llvm as the backend on my linux machine. I have a piece of Motorola 88100 code (essentially the output of the 176.gcc benchmark from SPEC CPU 2000) that I am trying to run using this emulator, but I am running into errors when trying to run it. Has anyone been able to successfully use the m88k

Hallo, yesterday I was puzzled when I discovered that I probabliy miss something in the interepretation of intercept in two-way lm models. I thought that the intercept, using the default contr.treatment contrasts, represents the mean of the group of observations having zero in all column of the model.matrix. It turns out not to be case To be more more clear I am attaching a short example:
