2009-10-13Teach sema and codegen about the difference between address of labels,Chris Lattner
which is a common idiom to improve PIC'ness of code using the addr of label extension. This implementation is a gross hack, but the only other alternative would be to teach evalutate about this horrid combination. While GCC allows things like "&&foo - &&bar + 1", people don't use this in practice. This implements PR5131. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83957 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13reimplement codegen for indirect goto with the following advantages:Chris Lattner
1. CGF now has fewer bytes of state (one pointer instead of a vector). 2. The generated code is determinstic, instead of getting labels in 'map order' based on pointer addresses. 3. Clang now emits one 'indirect goto switch' for each function, instead of one for each indirect goto. This fixes an M*N = N^2 IR size issue when there are lots of address-taken labels and lots of indirect gotos. 4. This also makes the default cause do something useful, reducing the size of the jump table needed (by one). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83952 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13number address-taken labels from 1. This allows 0 to be used as a sentinelChris Lattner
for a null pointer. In other words, "&&foo != NULL" will always work out to true. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83948 91177308-0d34-0410-b5e6-96231b3b80d8
