Hello, when I do try to start a program with g++ options -g -O0 ( all optimizations turned off I get ) :

so far my understanding of this code is :
Code: Select all
VertexElementSemantic GLSLProgramCommon::getAttributeSemanticEnum(const String& type)
{
size_t numAttribs = sizeof(msCustomAttributes)/sizeof(CustomAttribute);
for (size_t i = 0; i < numAttribs; ++i)
{
if (msCustomAttributes[i].name == type)
return msCustomAttributes[i].semantic;
}
OgreAssertDbg(false, "Missing attribute!");
return VertexElementSemantic(0);
}for parameter type = "aPos" should be rised up......
because the msCustomAttributes is equall to :
Code: Select all
(gdb) print msCustomAttributes
$9 = {{name = 0x7ffff413333d "vertex", attrib = 0, semantic = Ogre::VES_POSITION},
{name = 0x7ffff4133344 "position", attrib = 0, semantic = Ogre::VES_POSITION},
{name = 0x7ffff413334d "blendWeights", attrib = 1, semantic = Ogre::VES_BLEND_WEIGHTS},
{name = 0x7ffff413335a "normal", attrib = 2, semantic = Ogre::VES_NORMAL},
{name = 0x7ffff4133361 "colour", attrib = 3, semantic = Ogre::VES_COLOUR},
{name = 0x7ffff4133368 "secondary_colour", attrib = 4, semantic = Ogre::VES_COLOUR2},
{name = 0x7ffff4133379 "blendIndices", attrib = 7, semantic = Ogre::VES_BLEND_INDICES},
{name = 0x7ffff4133339 "uv0", attrib = 8, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff4133386 "uv1", attrib = 9, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff413338a "uv2", attrib = 10, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff413338e "uv3", attrib = 11, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff4133392 "uv4", attrib = 12, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff4133396 "uv5", attrib = 13, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff413339a "uv6", attrib = 14, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff413339e "uv7", attrib = 15, semantic = Ogre::VES_TEXTURE_COORDINATES},
{name = 0x7ffff41333a2 "tangent", attrib = 14, semantic = Ogre::VES_TANGENT},
{name = 0x7ffff41333aa "binormal", attrib = 15, semantic = Ogre::VES_BINORMAL}}
Why is it good to use " layout (location = 0) in vec4 aPos; " in my shader programs in Relase mode , and why it is bad to use it in suppressed optimization mode ?
