similar to: [LLVMdev] lldb cannot display structure type for llvm3.2

This may be a debug info bug, if you could reduce it down a bit and file a bug that'd be appreciated. Thanks. -eric On Sun, Jan 27, 2013 at 12:11 AM, Jonathan <gamma_chen at yahoo.com.tw> wrote: > I find the lldb cannot display structure type information, such as "print > ArgLocs.size()" as follows, > > -> 593 CCValAssign &VA = ArgLocs[i]; >

Hi Arnold, Thanks for the patch. Some questions and commons: 1. Have you test it against the llvm test suite? Does it work if fp elimination optimization is turned off? 2. Please follow llvm coding convention and make sure every line fits in 80 columns. 3. enum NameDecorationStyle { None, StdCall, - FastCall + FastCall, + FastCC // the normal fastcc calling convention }; Why is

Hi Evan, first off thanks to you and Chris for taking time.

Hi, I define a customized node with customized type. The job of this customized node is to move a value from one register class to another class. I find that if there is no use of the destination register, this node will be deleted from SDAG. For some reasons, I want to keep this node. So I attach mayStore attribute to this node and I hope it will not be deleted. However, it does not work like I

Hi, I would like to start a new porting of GlobalIsel for RISCV. An initial patch about GlobalIsel infrastructure for RISCV was ready now: https://reviews.llvm.org/D65219 There is another porting patch https://reviews.llvm.org/D41653 posted by Leslie Zhai at the end of 2017. I have checked with Leslie about the status of this patch.He has stopped developing it since some questions need be

Thanks. More questions :-) /// Information about how the value is assigned. - LocInfo HTP : 7; + LocInfo HTP : 6; Do you know why this change is needed? Are we running out of bits? - NeededStackSize = 4; - break; - case MVT::i64: - case MVT::f64: - if (firstGPR < 3) - NeededGPRs = 2; - else if (firstGPR == 3) { - NeededGPRs = 1; - NeededStackSize = 4; -

Although it's not generally needed for ARM's use of CCCustom, I return two bools to handle the four possible outcomes to keep the mechanism flexible: * if CCCustomFn handled the arg or not * if CCCustomFn wants to end processing of the arg or not I placed the "unsigned i" outside those loops because i is used after the loop. If there's a better index search pattern, I'd

I think I've got all the cases handled now, implementing with CCCustom<"foo"> callbacks into C++. This also fixes a crash when returning i128. I've also included a small asm constraint fix that was needed to build newlib. deep On Mon, Jan 19, 2009 at 10:18 AM, Evan Cheng <evan.cheng at apple.com> wrote: > > On Jan 16, 2009, at 5:26 PM, Sandeep Patel wrote:

Are we running out of bits? HTP was't using all of these bits. I needed the hasCustom bit to come from somewhere unless we wanted to grow this struct, so I

I'm not currently setup to be able to run the A/B comparison tests that test-suite relies upon. Fhourstones-3.1 looks to be the simplest. If you can send me the two .o files from either EABI or Darwin, I can dig into why this went wrong for you. deep On Thu, Feb 26, 2009 at 3:53 PM, Evan Cheng <echeng at apple.com> wrote: > Sorry I haven't gotten back to you earlier.

Thanks Sandeep. I did a quick scan, this looks really good. But I do have a question: +/// CCCustomFn - This function assigns a location for Val, possibly updating +/// all args to reflect changes and indicates if it handled it. It must set +/// isCustom if it handles the arg and returns true. +typedef bool CCCustomFn(unsigned &ValNo, MVT &ValVT, + MVT

Sorry I haven't gotten back to you earlier. I have been busy. I ran some MultiSource/Benchmark earlier today. Looks like there are some failures: Fhourstones-3.1, Fhourstones, McCat/08-main, MiBench/ consumer-lame, Olden/Power, Olden/voronoi, mafft/pairlocalign, and sim. Are you able to test them on your end? Evan On Feb 17, 2009, at 4:42 PM, Sandeep Patel wrote: > This time with
