It fails on x86 using x87 floating point, with the inliner not run,
because of 1505, yes. Gonsolo, is that your situation?
(What happens is, there is a wrapper in the header file for std::tan
(float),
like this:
inline float
tan(float __x)
{ return __builtin_tanf(__x); }
This wrapper is miscompiled due to 1505; when the inliner is run, no
problem.)
(But, when opt -std-compile-o...

I tried a simple "llvm-g++ -o simple tan.bug.cc"
Output:
tan float: -2.18504
tan double: 0.309336

<end tangens_bug.cc>
Result compiled with g++ 4.1:
tan float: 0.309336
tan double: 0.309336
Result compiled with llvm-g++ 2.0:
tan float: -2.18504
tan double: 0.309336
Am I missing something or should I file a bug report?
Thanks,

Can you try LLVM r97474? r97475 enabled the new isel by default
which started to crash our out-of-tree backend (we also use inline asm
even in crt0()), maybe this is related. I've been tracking...

[LLVMdev] JIT slow
Hi!
It appeared to me that runFunction in JIT.cpp is slow for repeatedly
executing the same function with nontrivial arguments since the "Stub"
function in JiT.cpp:183 (LLVM 1.9) is compiled again and again.
Is there something I can do to accelerate this?

This may be due to bug 1505.
Ciao,

[LLVMdev] Strange Multiple Inheritance Errors Using LLVM 2.7
Dear All,
I'm currently upgrading SAFECode to the LLVM 2.7 API. I'm getting some
strange errors in LLVM Passes that use analysis groups and multiple
inheritance.
To create analysis groups in LLVM 2.6, I would first create a base class
for the analysis group and then another class that inherited from both
ModulePass and the analysis group base class. That worked in LLVM 2.6,
but
