gcc 2.95.2/irix/Laguerre_With_Deflation/inifinte loop
I built ogg vorbis from the rc1 cvs source on Irix 6.5.12
with gcc 2.95.2. Using oggenc I encoded about 8,000 aiff files
but found about a dozen where oggenc would go into an infinite
loop. I tracked the problem with Laguerre_With_Deflation() as far back
as
logmask being Inf in floor0_forward. I'm now building gcc 3.0 with the
expectation this is a compiler issue. If not, I'll back

llvm.rint specification
Hello,
I believe llvm.rint description in LangRef is not quite complete.
Llvm seems to map math.h:rint() call to llvm.rint intrinsic, and the LangRef says that the result of llvm.rint matches the result of libm rint() call. Next, LangRef states that llvm.rint "returns the operand rounded to the nearest integer."
Shouldn't the specification also say that "the actual rounding

llvm.rint specification
Hi Cameron,
Thank you for the comments, but I am confused even more now ☺
> llvm.rint won't honor the FPEnv in all cases. It falls under the default FPEnv
The default FPEnv section specifies round-to-nearest rounding mode. In this case, how is it correct to map rint() user call to llvm.rint intrinsic call? If this is just a temporary inconsistency, and the long term solution is to map

Are the error messages of ConstrOptim() consisten with each other?
Dear Friends.
I found something very puzzling with constOptim(). When I change the
parameters for ConstrOptim, the error messages do not seem to be
consistent with each other:
> constrOptim(c(0.5,0.3,0.5), f=fit.error, gr=fit.error.grr, ui=ui,ci=ci)
Error in constrOptim(c(0.5, 0.3, 0.5), f = fit.error, gr = fit.error.grr, :

Building theora 1.1.1 with mingw-w64-gcc 7.1 and msys
Hello,
I recently attempted to build theora 1.1.1 with mingw-w64-gcc 7.1 and
msys and it fails to build the encoder_example.c example program. There
are multiple declarations of the function 'rint'. The source file
created its own version of the function that rounds AWAY from zero.
MinGW-W64 has its own version of the 'rint' function, which does not
round away from zero.

Should rint and nearbyint be always constrained?
Some clarification after getting feedback from Craig Topper….
It’s probably best to say in the documentation that the llvm.nearbyint and llvm.rint functions “assume the default rounding mode, roundToNearest”. This will allow the optimizer to transform them as if they were rounding to nearest without requiring backends to use an encoding that enforces roundToNearest as the rounding mode for these

Compiling with GCC on win32?
Why does the source use `int64_t'. Is this suppose to be built
with GCC? I have Mumit Kahns gcc, version 2.8.1. Do I need a
2.9.5 version to get the `int64_t' type? I have substituted a
typedef of `long long' in os_types.h. This seems to make sense?
The rint() macro also seems to be having some problems. I guess
there are two meanings to __GNUC__ and _WIN32. One is the OS and

Problems linking against libvorbis.a with GnuWin32
I'm trying to link against libvorbis.a using GnuWin32
without the Cygwin layer (that is, Mingw32). Unfortunately
the linker complains about a missing function: rint().
This function is used a couple of times in libvorbis and
as far as I understand this is a standard C library function.
My problem is, that I cannot find rint() in any of the common DLLs
nor do I know how MSVC resolves this

Problems supporting rint.
I am coding with vorbis using mingw32 (g++ for win32 without the cygwin.dll
dependency). mingw32's math library does not support rint and I can't find
a replacement so I have tried the following:
Use Cygwin to execute ./configure.
Then:

I am a mingw coder and I needed to make the following changes to the CVS source from 9/13/00 to get a build:

fenv.h vs the optimizer
Howdy all,
I've been playing around with programs that use the C11 fenv.h.
It seems that, currently, the LLVM compiler does not regard to the
exception-flag side-effects of floating point operations?
When run on my macbook, the example code on
http://en.cppreference.com/w/c/numeric/fenv/FE_exceptions does not print
all the expected exceptions.

vorbis under win32
Hello Monty,
I tried to complile vorbis under win32 (using MS Visual C 5.0)
I found some things:
1.)
In bitvise.c there must be buffer cleared after malloc:
void _oggpack_writeinit(oggpack_buffer *b){
memset(b,0,sizeof(oggpack_buffer));
b->ptr=b->buffer=malloc(BUFFER_INCREMENT);
+ memset(b->ptr,0,BUFFER_INCREMENT);
b->storage=BUFFER_INCREMENT;
