This enabled opaque pointers by default in LLVM. The effect of this is twofold: * If IR that contains *neither* explicit ptr nor %T* types is passed to tools, we will now use opaque pointer mode, unless -opaque-pointers=0 has been explicitly passed. * Users of LLVM as a library will now default to opaque pointers. It is possible to opt-out by calling setOpaquePointers(false) on LLVMContext. A cmake option to toggle this default will not be provided. Frontends or other tools that want to (temporarily) keep using typed pointers should disable opaque pointers via LLVMContext. Differential Revision: https://reviews.llvm.org/D126689
This reverts commit 83a798d4b0e17ac41d5430f1290d3661343eee1e. As discussed in D120714 with @thakis, the patch added unneeded complexity without noticeable benefits.
Place PersistentId declaration under #if LLVM_ENABLE_ABI_BREAKING_CHECKS to reduce memory usage when it is not needed. Differential Revision: https://reviews.llvm.org/D120714
These are identical but use microMIPS instructions instead of MIPS instructions. Also, flatten the 'let AdditionalPredicates = [InMicroMips]' by using the ISA_MICROMIPS adjective. Add tests for constant materialization. Reviewers: atanasyan, abeserminji, smaksimovic Differential Revision: https://reviews.llvm.org/D48275 llvm-svn: 335185

This patch makes one change to GOT handling and two changes to N64's relocation model handling. Furthermore, the jumptable encodings have been corrected for static N64. Big GOT handling is now done via a new SDNode MipsGotHi - this node is unconditionally lowered to an lui instruction. The first change to N64's relocation handling is the lifting of the restriction that N64 always uses PIC. Now it is possible to target static environments. The second change adds support for 64 bit symbols and enables them by default. Previously N64 had patterns for sym32 mode only. In this mode all symbols are assumed to have 32 bit addresses. sym32 mode support is selectable with attribute 'sym32'. A follow on patch for clang will add the necessary frontend parameter. This partially resolves PR/23485. Thanks to Brooks Davis for reporting the issue! This version corrects a "Conditional jump or move depends on uninitialised value(s)" error detected by valgrind present in the original commit.
