With this patch we use simple names for COMDAT sections (like .text or .bss). This matches the MSVC behavior. When merging it is the COMDAT symbol that is used to decide if two sections should be merged, so there is no point in building a fancy name. This survived a bootstrap on mingw32. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195823 91177308-0d34-0410-b5e6-96231b3b80d8

This is the first step to fix pr17918. It extends the .section directive a bit, inspired by what the ELF one looks like. The problem with using linkonce is that given .section foo .linkonce.... .section foo .linkonce we would already have switched sections when getting to .linkonce. The cleanest solution seems to be to add the comdat information in the .section itself. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195822 91177308-0d34-0410-b5e6-96231b3b80d8

Short description. This issue is about case of treating pointers as integers. We treat pointers as different if they references different address space. At the same time, we treat pointers equal to integers (with machine address width). It was a point of false-positive. Consider next case on 32bit machine: void foo0(i32 addrespace(1)* %p) void foo1(i32 addrespace(2)* %p) void foo2(i32 %p) foo0 != foo1, while foo1 == foo2 and foo0 == foo2. As you can see it breaks transitivity. That means that result depends on order of how functions are presented in module. Next order causes merging of foo0 and foo1: foo2, foo0, foo1 First foo0 will be merged with foo2, foo0 will be erased. Second foo1 will be merged with foo2. Depending on order, things could be merged we don't expect to. The fix: Forbid to treat any pointer as integer, except for those, who belong to address space 0. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195810 91177308-0d34-0410-b5e6-96231b3b80d8

Summary: Moved the requirement for SelectionDAG::getConstant() to return legally typed nodes slightly earlier. There were two optional DAGCombine passes that were missed out and were required to produce type-legal DAGs. Simplified a code-path in tryFoldToZero() to use SelectionDAG::getConstant(). This provides support for both promoted and expanded vector types whereas the previous code only supported promoted vector types. Fixes a "Type for zero vector elements is not legal" assertion detected by an llvm-stress generated test.
