Hello,
I am working on gcc-4.9.4 and encountered different results of loop
vectorization on array arr0, arr1 and arr2.
Testcase -
int main()
{
int i;
for (i=0; i<64; i++)
{
arr2[i]=(arr1[i]|arr0[i]);
}
}
Using -O2 -ftree-vectorize, Above loop is vectorized if arr

Hello,
Is there a direct way to print the name of the function call in gimple call
statement?
For example -
void bar() {
a = foo();//gimple* stmt
}
I want to print "foo" from the above gimple*.
I traced debug_gimple_stmt(gimple*) but it seems complex to just print
"foo".
Thanks and R

Hello,
I have a PHI node that defines a variable that is used in 1 statement. I
then delete the statement. I think I need to update the PHI node to no
longer reference that variable. I looked through some code and I don't see
a way to just remove an element from a PHI node and I see in the file

Hello,
My aim is to iterate over gimple call stmt parameters and check
whether it is constant or constant expression and mark/store them for
some gimple transformation.
I have an intrinsic function call of the following -
__builtin_xyz(void*, 7, addr + 10);
I want to find its parameters which a

Hello,
Is it possible to generate a NOTE instruction at GIMPLE level?
My use case scenario is as below -
I want to create a note for __builtin_xyz(_x) such that there is a
placeholder just before function call and in RTL pass, I want to
modify/assign register number at this placeholder location.
Hello,
I want to know whether it is correct to add left shift instruction to
a constant expression statement like "_3 + 4"?
I am trying to add a left shift instruction in between below GIMPLE
instructions -
:
instrn_buffer.0_1 = instrn_buffer;
_2 = tree.cnt;
_3 = (int) _2;
_4 = _3 + 4

Hello,
I want to collect complete rtl instruction corresponding to below gimple
call - "__builtin_temp"
I have gimple instructions of form -
slli_31 = _2 << 8;
srli_32 = slli_31 >> 8;
add_33 = srli_32 + 15;
_20 = __builtin_temp (instrn_buffer.36_1, 1, add_33);
For that, I put breakpoint in expa
Hello,
[1] I want to achieve hosting of a custom built-in call out of loop that

slli_6 = _9 << 8;
srli_36 = slli_6 >> 8;
li_37 = __builtin_load_immediate (15);//I want to hoi
