similar to: [Unsafe-fp-math] Merge attribute for inlining

Hal, Thanks for the reply. I am trying to understand the underlying concern. That means the inlining of a callee without unsafe-fp-math attribute set will block the unsafe optimization in its caller, right? Thanks, Yan From: Finkel, Hal J.

Hi all. I keep getting the error in the subject line whenever attempting to put Syslinux onto the floppy. As a result, it refuses to write ldlinux.sys. I have tried most if not all the viable combinations, and Syslinux still complains. Anyone know what permissions Syslinux espect on /tmp? I have not been able to determine this so far. Thanks! Yours Li Haijun

Hello again, I sent in this error a couple weeks ago and one person (eric) kindly responded and tried to help, but to no avail. Any one else have any ideas on the following: A couple years ago I installed Samba 2.2.0 on our HP9000 running HPUX 10.20. I am now trying to install it on a customer's HP9000 (also using 10.20) and executing the configure command produces the "No locking

The current libxl_set_memory_target function subtracts a negative amount from an uint32_t variable without checking if the operation wraps around.

Hello, My idea is to detect a multithreading and perform some transformations and get new possibilities for optimizations: 1. Check pthread_create and follow CallInstr (goal: to know that we are in new thread), identify functions where fork is used and check all other CallIstr (we are in child) + check Windows variants of fork/ thread create.. 2. Check functions if they do not contain any of

Hi Bill, > The current implementation of the "allow unsafe math" option is to specify it via the TargetOptions object. However, this prevents the target-independent optimizer from using it. Are there any opinions (ha!) on how this could be achieved in a nice clean manner which doesn't require using the TargetOptions object in the optimizer? a flag on each floating point

I use FoldingSet to save some data structures. And I found somehow it always abandon a new node. I tracked the bug into the ComputeHash() function of FoldingSet. It computes the SAME hash value for these two 32-bit unsigned integer sequences: size: 17

I tried a simple float math (a + b - b) using llc's option –enable-unsafe-fp-math, but I still have add and sub in the code (x86). Does LLVM perform any float/double reassociation, etc under unsafe math or fast-math ? Thanks Junjie

I would probably support doing that first. A small annoyance is that the linker
