This patch adds a number of fp instructions needed for OS/2 to boot as a HVM guest on Intel/VT hardware. It appears to work fine, and OS/2 is now finally working on Intel/VT as well as AMD/SVM. I''m a little concerned about the "correctness" of the FSTSW emulation and the use of inline assembly directly using the corresponding ops for emulation. Wrt FSTSW, it is really two ops

Hello, I've built LLVM natively on a fpu-less (soft-float) mips32 target, and built mesa to use it. However llvm apparently cannot determine what machine it's running on and builds code for a generic mips target with fpu. Is there a way to have llc/llvm always use "-march=mipsle -mcpu=mips32 -mattr=+soft-float" as a default...

Hi Siarhei, if you can get us the sequence of attributes you want emitted for each fpu type, and what you expect to see on the .o side, it should be very possible to get...

...it up and submit the patch. Thanks for reminding about it. Hi Renato, I noticed that support for some elf eabi attributes has been added to LLVM and it is a good progress. But still this is insufficient. Now with the schedule for 2.9 available, would it be possible to resolve this missing ".fpu" directive issue for 2.9 release in order to have clang working on ARM linux systems out of the box without patching? Thanks. -- Best regards, Siarhei Siamashka

Hi Mike, sorry, but somehow I can't understand this patch... I'll try to read it with a fresh head on Weekend, but for example, On 06/01, Mike Christie wrote: > > static int vhost_task_fn(void *data) > { > struct vhost_task *vtsk = data; > - int ret; > + bool dead = false; > + > + for (;;) { > + bool did_work; > + > + /* mb paired w/

Dear developers, is there (already) a platform-independent way for (temporarily!) changing the fpu control word? More precisely: I am looking for functions (accessible from C code in R packages) which read and write the fpu control word on x86 cpus (and cause no harm otherwise), because I need to (temporarily) turn off internal 80-bit precision for some algorithms relying on 64-bit IEEE arit...

Hi, While testing ReplayGain (so it could be related to a bug), I noticed the following gain comments for a file: RG_PEAK=1.71580 RG_RADIO=-7.91 dB RG_AUDIOPHILE=-6.72 dB I've never seen such a large peak. Not that I've looked much, nor have I analyzed the file further. I just thought I should mention it. :) The file is the track Board Burner by Mixmaster Mike, available at:
