// Bug: Qualcomm has broken ivec to scalar and ivec to ivec bitshifts
// Affected devices: Adreno
// Started Version: -1
// Ended Version: 46 (TODO: Test more devices, the real end is currently unknown)
// Qualcomm has broken integer vector to integer bitshifts, and integer vector to integer vector bitshifts
// A compilation error is generated when trying to compile the shaders.
//
// For example:
// Broken on Qualcomm:
// ivec4 ab = ivec4(1,1,1,1);
// ab <<= 2;
//
// Working on Qualcomm:
// ivec4 ab = ivec4(1,1,1,1);
// ab.x <<= 2;
// ab.y <<= 2;
// ab.z <<= 2;
// ab.w <<= 2;
//
// Broken on Qualcomm:
// ivec4 ab = ivec4(1,1,1,1);
// ivec4 cd = ivec4(1,2,3,4);
// ab <<= cd;
//
// Working on Qualcomm:
// ivec4 ab = ivec4(1,1,1,1);
// ivec4 cd = ivec4(1,2,3,4);
// ab.x <<= cd.x;
// ab.y <<= cd.y;
// ab.z <<= cd.z;
// ab.w <<= cd.w;
