Tom Lane	640a4ba052	Postpone LLVM-related uses of AC_CHECK_DECLS. ... Calling AC_CHECK_DECLS before we've finished setting up the compiler's CFLAGS seems like a pretty risky proposition, especially now that the first use of that macro will result in a test to see whether the compiler gives warning or error for undeclared built-in functions. That answer could very easily get changed later than where PGAC_LLVM_SUPPORT is called; furthermore, it's hardly unlikely that flags such as -D_GNU_SOURCE could change visibility of declarations. Hence, be a little less cavalier about where to do LLVM-related tests. This results in v11 and HEAD doing the warning-or-error check at the same place in the script as older branches are doing it, which seems like a good thing. Per further thought about commits 0b59b0e8b and 16fbac39f.	7 years ago
Andres Freund	240d40db88	Detect LLVM 7 without specifying binaries explicitly. ... Before this commit LLVM 7 was supported, but only if one explicitly provided LLVM_CONFIG= and CLANG= paths. As LLVM 7 is the first version that includes our upstreamed debugging and profiling features, and as debian is planning to default to 7 due to wider architecture support, it seems good to support auto-detecting that version.

Andres Freund	cb92520563	LLVMJIT: LLVMGetHostCPUFeatures now is upstream, use LLMV version if available. ... Noticed thanks to buildfarm animal seawasp. Author: Andres Freund Backpatch: v11-, where LLVM based JIT compliation was introduced.	7 years ago
Andres Freund	e9a9843e13	LLVMJIT: Adapt to API changes in gdb and perf support. ... During the work of upstreaming my previous patches for gdb and perf support the API changed. Adapt. Normally this wouldn't necessarily be something to backpatch, but the previous API wasn't upstream, and at least the gdb support is quite useful for debugging.

Andres Freund	5b2526c838	Add configure infrastructure (--with-llvm) to enable LLVM support. ... LLVM will be used for *optional* Just-in-time compilation support. This commit just adds the configure infrastructure that detects LLVM. No documentation has been added for the --with-llvm flag, that'll be added after the actual supporting code has been added.
