Need help in understanding llvm optimization
I am sorry to not make my question clear. My question is how this value is
calculated without having fadd and fsub in IR?

Need help in understanding llvm optimization
Hi,
I have below code in C -
int main() {
double x,y;
x = 1e16;
y = (x + 1) - x;
printf("y:%e\n", y);
return 0;
}
llvm bitcode looks like this for this function -

%call = tail call i32 (i8*, ...) @printf(i8* getelementptr inbounds ([4 x

Documentation/software inconsistency in `:` and seq
...ge.mode(seq(from=1L,to=2.5)) => integer
---------------------------------
On the other hand, according to ? seq
Currently, the default method returns a result of type '"integer"'
if 'from' is (numerically equal to an) integer
This is not correct:
> seq(1e16,1e16+10)
[1] 1e+16 1e+16 1e+16 1e+16 1e+16 1e+16 1e+16 1e+16 1e+16 1e+16 1e+16
> seq(1e16,1e16+10)-1e16
[1] 0 0 2 4 4 4 6 8 8 8 10 # not enough precision to represent
all the distinct integers, OK

bessel_?.c constants
Hi All,
I've been digging around in src/nmath and have discovered that there are
two sets of "machine constants" in bessel_l.c and bessel_j.c which have
different values:
bessel_i.c: static double ensig = 1e16;
bessel_i.c: static double rtnsig = 1e-4;
bessel_i.c: static double enmten = 8.9e-308;
bessel_i.c: static double enten = 1e308;
bessel_j.c: static double ensig = 1e17;
bessel_j.c: static double rtnsig = 1e-4;
bessel_j.c: static double enmten = 1.2e-37;

missing PROTECT() in src/main/arithmetic.c
at lines 651 & 653 (integer_binary function):
if (code == DIVOP || code == POWOP)
ans = allocVector(REALSXP, n);
else
ans = allocVector(INTSXP, n);
There are calls to warningcall() later in the function, which can
trigger garbbage collection.
Looks like the typical scenario where it seemed pretty safe to not
PROTECT in the original version of the function but

Hey Richard,
Could you share the following informations please?
1. gluster volume info <volname>
2. getfattr output of that file from all the bricks
getfattr -d -e hex -m . <brickpath/filepath>
3. glustershd & glfsheal logs

On a side note, try recently released health report tool, and see if it
does diagnose any issues in setup. Currently you may have to run it in all
the three machines.
