similar to: RFC: No Control Flow Check Attribute

Here in an example that explains the difference. // Only declaration – No implementation // Assume that the value is returned in EAX and the arguments are passed in EAX, ECX, EDX, ESI, EDI. int __regcall callee (int a, int b, int c, int d, int e); // implemented in a different module void caller() { … x = callee(1,2,3,4,5); … } What will be RegMask using IPRA register usage collector? Callee

Hi Mehdi, I think that the subject of the RFC is misleading. The true problem that we are trying to solve is to remove returned/passed arguments from the regmask (According to the calling convention). IPRA and CC updated RegMask can’t use the same mechanism because they contradict each other. I think that the following analog will help to explain why I think that a reuse is redundant: Let’s

I think we should wait until there is someone wanting to use these features with lld.

Hi Mehdi, It is true that both IPRA and the proposed mechanism save RegMasks. So you might say that the data structure in the immutable pass should be reused, but this is the only similarity. Even this similarity is not exactly true. I save register masks that doesn’t use passed/returned arguments while IPRA saves register masks for modified registers. So how can they share the same mechanism?

Linux GABI [1] introduced new .note.gnu.property section which contains a program property note which describes special handling requirements for linker and run-time loader. LLD does not support .note.gnu.property yet. GABI specifies 2 types of entries: GNU_PROPERTY_STACK_SIZE and GNU_PROPERTY_NO_COPY_ON_PROTECTED: * GNU_PROPERTY_STACK_SIZE: Its pr_data field contains an integer in the format

Hi Mehdi, I wasn’t familiar with IPRA before, thank you for bringing it up. After studying it, I have to say that IPRA is a wonderful idea and is well implemented. I tried to reuse the mechanism for the last couple of days. I implemented a solution using IPRA mechanism and encountered few issues: 1. IPRA uses immutable analysis pass called “PhysicalRegisterUsageInfo”. The usage of such

Hi, I want to add Target Specific MachineFunctionPass so that it will run during Link Time Optimization. The pass is currently running in non-LTO compilation (added in addPreEmitPass). What do I need to do in order to run my pass also during LTO?

Hi All, The Register Calling Convention (RegCall) was introduced by Intel to optimize parameter transfer on function call. This calling convention ensures that as many values as possible are passed or returned in registers. To use RegCall, place the keyword before a function declaration. For example: __regcall int foo (int i, int j); // Windows OS __attribute__((regcall)) foo (int I, int j); //

Hello. Can anyone please take a second to help me out with this problem? I try to run Longman iBT 2.0 Toefl with the last version of Wine / Lubuntu / FGLRX (video driver for ATI HD 4330 ) / Java. I have the last version of all these... As you can see, the program runs but some items are not displayed or wrong displayed. Moving the pointer or moving the window can make the image better or worse.

I want to estimate the effect of several independent variables on several dependent variables. In the example below I wanted to estimate the effect of three independent variables on ozone and temperature. My aim is to create a list of dependent and independent variables and automate the process rather than writing every dependent and independent variable in each model as I have done below.

Adding Support For Vectorcall Calling Convention ===================================================== Vectorcall Calling Convention for x64 ---------------------------------------------------- The __vectorcall calling convention specifies that arguments to functions are to be passed in registers, when possible. __vectorcall uses more registers for arguments than __fastcall or the default x64

Hi, I get strange time entries in the rsync log, For example: 2006/07/02 14:56:12 [20054] rsync to upload/aspen/nhm from plxc6266.pdx.intel.com (10.25.26.90) 2006/07/02 11:56:22 [20054] wrote 28 bytes read 3582404 bytes total size 32030720 The first entry in the correct time and second is strange.

Hi, We use rsync to share data between two remote sites. We are using rsync after configuration of the rsync.conf file. I created a module in the file with the relevant entries and permissions. The problem is that I get "connection refused ", when I try to run rsync in the following way: root@rsync1-mpg:/root# rsync ptsinf01.pt.intel.com:: rsync: failed to connect to

Dynamically Allocated "Callee Saved Registers" Lists Each Calling convention (CC) defines a static list of registers that should be preserved by a callee function. All other registers should be saved by the caller. Some CCs use additional condition: If the register is used for passing/returning arguments - the caller needs to save it - even if it is part of the Callee Saved Registers

Hi All, I am trying to run rsync from HP11.00 machine (source) to HP11.11 machine, as test for migration plan. The data on the source is not changing since it is snapshot of active data. Every time we try to run the following command: timex rsync -avuz --delete isynh09:/snap We get the following error: receiving file list ... done mknod

Hi, I have a problem rsync disk that is linked in the following way: /a/b/c/d/e -> ../e We use that in order to create linked tree which has link to kind of tools we need to rsync and thus not worry on disk capacity cause we can add linked disks as many as we can. We use rsync module with chroot for security reasons as follows: [d] Path = /a/b/c/d Chroot = true The

Hi, I use rsync daemon to replicate disks between sites. I am replicating the disks using rsync -avzx command. The thing is that I have in one site the same UNIX group but with different GID. So someone with the same UID can access the group on the source but not on the destination. Is there a way, beside aligning GID number, on both sites to after changing the group on the destination
