Notably extra white spaces or scopes are removed. When the loop nesting or
expression is deep, the emitted becomes unreadable.
Before:
`extern "C" __global__ void test_kernel0(void* __restrict__ B, void*
__restrict__ A) {
float4 _1;
{
float4 _2 = (( float4*)(( float*)A + ((((int)blockIdx.x) * 4))))[0];
float4 _3 = make_float4(1.000000e+00f, 1.000000e+00f, 1.000000e+00f,
1.000000e+00f);
_1.x = (_2.x+_3.x);
_1.y = (_2.y+_3.y);
_1.z = (_2.z+_3.z);
_1.w = (_2.w+_3.w);
}
(( float4*)(( float*)B + ((((int)blockIdx.x) * 4))))[0] = _1;
}`
After:
`extern "C" __global__ void test_kernel0(void* __restrict__ B, void*
__restrict__ A) {
float4 _1;
float4 _2 = ((float4*)((float*)A + ((((int)blockIdx.x) * 4))))[0];
float4 _3 = make_float4(1.000000e+00f, 1.000000e+00f, 1.000000e+00f,
1.000000e+00f);
_1.x = (_2.x+_3.x);
_1.y = (_2.y+_3.y);
_1.z = (_2.z+_3.z);
_1.w = (_2.w+_3.w);
((float4*)((float*)B + ((((int)blockIdx.x) * 4))))[0] = _1;
}`
