clang 4.0.0: Invalid code for builtin floating point function with -mfloat-abi=hard -ffast-math (ARM)
Hello,
clang/llvm 4.0.0 generates invalid calls for builtin functions with
-mfloat-abi=hard -ffast-math.
Small example fail.c:
// clang -O2 -target armv7a-none-none-eabi -mfloat-abi=hard
-ffast-math -S fail.c -o -
extern float sinf (float x);
float sin1 (float x) {return (sinf (x));}
generates code to pass the parameter in r0 and expect the result in r0.
The same code without -ffast-math compiles correctly. It also works with
-fno-builtin-sinf.
(-O2 is not required to trigger the bug, but makes the resulting code
easier to read)
It seems -ffa...

I changed your example slightly to make sure we're passing the
arguments, otherwise 'sin1' just becomes 'b sinf', which is "correct"
on both hard and soft float.
extern float sinf (float x);
float sin1 (float x, float y) {return (sinf (...

...ld like to make sure that I
got the output from (3) right. The ouput of (3) tells me that the highest
R^2 value was reached after 8 iterations and there are only 8 significant
predictors in this model ??? In addition the only significant frequencies
(predictors) left are:
cos1, cos2, cos4, cos7, sin1,sin2, sin3, sin5
I got this information interactively. But I'm in troubles at extracting it
automatically.
Any suggestion ?
Question: Do I have to run "step" in advance of "regsubsets" for a
first-pass model pruning or may I run "regsubsets" on the original mode...

[LLVMdev] floor
Here is a test case:
extern double floor(double);
extern double floor_(double);
double x = 1.5;
double y, y_;
void foo() {
double y = floor(x);
double y_ = floor_(x);
}
If I compile this for Mips16, it calls the proper helper function for
floor_ but not for floor, because the signature for floor in callee info
is wrong. Args[0] = void RetTy = void

[LLVMdev] floor
I'm getting some problems because it seems that the compiler is treating
"floor" differently from other math library functions like "sin".
The Args and RetVal have the parameter and return types marked as void.
For mips16, it's important that I be able to know the original signature
for floating point functions.
In some cases, need to create calls to helper
