* jit: Require at least LLVM 14, if enabled.Peter Eisentraut2024-10-01
| | | | | | | | | | Remove support for LLVM versions 10-13. The default on all non-EOL'd OSes represented in our build farm will be at least LLVM 14 when PostgreSQL 18 ships.

* jit: Changes for LLVM 17.Thomas Munro2023-10-19
| | | | | | | | | | | | Changes required by https://llvm.org/docs/NewPassManager.html. Back-patch to 12, leaving the final release of 11 unchanged, consistent with earlier decision not to back-patch LLVM 16 support either.

* jit: Supply LLVMGlobalGetValueType() for LLVM < 8.Thomas Munro2023-10-19
| | | | | | | | | | | Commit 37d5babb used this C API function while adding support for LLVM 16 and opaque pointers, but it's not available in LLVM 7 and older. Provide it in our own llvmjit_wrap.cpp. It just calls a C++ function that pre-dates LLVM 3.9, our minimum target. Back-patch to 12, like 37d5babb.

* jit: Support opaque pointers in LLVM 16.Thomas Munro2023-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove use of LLVMGetElementType() and provide the type of all pointers to LLVMBuildXXX() functions when emitting IR, as required by modern LLVM versions[1]. * For LLVM <= 14, we'll still use the old LLVMBuildXXX() functions. * For LLVM == 15, we'll continue to do the same, explicitly opting out of opaque pointer mode. * For LLVM >= 16, we'll use the new LLVMBuildXXX2() functions that take the extra type argument. The difference is hidden behind some new IR emitting wrapper functions l_load(), l_gep(), l_call() etc. The change is mostly mechanical, except that at each site the correct type had to be provided. In some places we needed to do some extra work to get functions types, including some new wrappers for C++ APIs that are not yet exposed by in LLVM's C API, and some new "example" functions in llvmjit_types.c because it's no longer possible to start from the function pointer type and ask for the function type. Back-patch to 12, because it's a little tricker in 11 and we agreed not to put the latest LLVM support into the upcoming final release of 11.

* llvmjit: Work around bug in LLVM 3.9 causing crashes after 72559438f92.Andres Freund2020-10-15
| | | | | | | | | | | | | | Unfortunately in LLVM 3.9 LLVMGetAttributeCountAtIndex(func, index) crashes when called with an index that has 0 attributes. Since there's no way to work around this in the C API, add a small C++ wrapper doing so. The only reason this didn't fail before 72559438f92 is that there always are function attributes...
