segfault with HowToUseJIT
Hi!
I've started looking porting our application which uses LLVM JIT to
using LLVM 9 (9.0.1).
To begin, I tried running the HowToUseJIT.cpp (example directory)
program and it fails with a segfault:
./HowToUseJIT
We just constructed this LLVM module:
; ModuleID = 'test'
source_filename = "test"
Running foo: Segmentation fault (core dumped)
Running it through GDB:
Program received signal SIGSEGV, Segmentation fault.
0x0000000000404912 in main () at HowToUseJIT.cc:131

llvm-link unifies identified structs?
...e] types are never
uniqued". But llvm-link seems to do just that at link-time:
> cat x.ll
%A = type {}
%B = type {}
%C = type { %A*, %B* }
define void @foo(%C* %c) {
ret void
}
> llvm-link x.ll | llvm-dis
; ModuleID = '<stdin>'
source_filename = "llvm-link"
%C = type { %A*, %A* }
%A = type {}
define void @foo(%C* %c) {
ret void
}
Does the statement in the language reference not apply to linking?
(This is with a recent 3.9).

Instcombine Creating Illegal Code? (in LLVM 7)
...all void @callee()
ret void
}
define fastcc void @callee() {
entry:
%malloccall = call i8* @malloc(i64 9)
store i8 0, i8* %malloccall
ret void
}
It get's transformed into the following invalid code after the optimization
(now having an illegal store):
; ModuleID = 'blarg.ll'
source_filename = "blarg.ll"
declare i8* @malloc(i64)
define void @caller() {
entry:
store i1 true, i1* undef, align 1
ret void
}
define fastcc void @callee() {
entry:
ret void
}
Anyone seen this before and/or could shed some light on this behavior.

"corrupted size vs. prev_size" when calling ExecutionSession::lookup()
...:cantFail(ES.lookup({&ES.getMainJITDylib()},
Mangle("main")));
int (*entry)() = (decltype(entry)) symbol.getAddress();
std::cout << entry() << std::endl;
and the "corrupted size vs. prev_size" will happen if the IR code is this:
; ModuleID = 'top'
source_filename = "top"
@0 = global [3 x i32] [i32 1, i32 2, i32 3]
define i32 @main() {

store i32 0, i32* %1
br label %2
; <label>:2: ; preds = %0
%3 = load i32, i32* %1
ret i32 %3
}
I put this IR code to lli, and it works fine....

Ensuring that dead allocations from a custom allocator are killed by LLVM

I have a custom allocator, and would like to teach LLVM about its

"dead", similar to dead new in C++.

; Function Attrs: inaccessiblememonly noinline norecurse nounwind
declare i8* @alloc(i64) local_unnamed_addr #0
; Function Attrs: inaccessiblememonly noinline norecurse nounwind

ThinLTO: module-scope inline assembly blocks
With `save-temps` as plugin option, I get extra files for the MAIN module
(called `a.o`): `a.o.opt.bc` and `a.thinlto.bc`.
The `a.thinlto.bc` file contains nothing, only `source_filename = ...` .
The `a.o.opt.bc` (this looks like the result after ThinLTO importing and
optimization) contains the assembly block that it should not have:
```

module asm "\09.globl\09foo"
