It prints "0". Calling that inifinity is somewhat of a stretch, isn't it ? What on earth

So, as far as I understood live intervals with weight equal to HUGE_VAL are spilled and I don't need to allocate physical registers for them, right?

Hi all, Someone please consider committing the attached patch. It fixes building recent revisions with Visual C++. (HUGE_VAL is needed by LiveInterval.cpp, and it's defined in math.h, which didn't get included for MSVC.) Cheers, Nicolas -------------- next part -------------- An HTML attachment was scrubbed...

...happens, reg_v' will receive a physical register. You must assign to reg_v' a weight such that is is not spilled again, otherwise you may enter on an infinite loop, always spilling the same spilled register.

DataTypes.h is transitively included through a lot of very common includes already. So its entirely possible AMDGPU and Hexagon are really including it.

all, this is all probably very old news and probably fixed in a later OSX, but..... on my 10.4.11 machine, math.h has (IMHO this bug) #define HUGE_VALF 1e50f this compiles when I build LLVM using "configure", but not with "cmake", probably to do with different C-standard-ness and pedantic-ness switches.... I would recommend LLVM Support not import the HUGE_VAL, HUGE_VALF feature, and instead use its own definition, I...

Hi! I'm developing a register allocator that works iteratively. It spills some virtual registers on each iteration until all the rest have physical ones assigned. How can I spill some live intervals at the end of each iteration with new live intervals having correct weights? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

It is also iterative: it uses the spiller interface to insert spill code, which creates (unspillable) intervals for the spill code it

First: R core: (Thank You!)^HUGE_VAL Now, down to business: In a loop or in repeated command lines: system.time(lm(rnorm(1000)~rnorm(1000))) ( or lm(rnorm(1000)~rnorm(1000))$coef ) fails after several iterations with the Windows message 'This program has performed an illegal operation and will be shut down.

I am experiencing some difficulties with vorbis on my LX164 alpha. Specifically, in bark_noise (psy.c) I see the following behaviour on the first pass through the function: val=-3.4e38 del=1 noise[0]+=val*del noise[1]-=val*del norm[0]+=del norm[1]-=del del=1 noise[1]-=val*del <== here is the problem At this point, noise[1]==3.4e38. We are trying to add another 3.4e38 to it and this is
