similar to: SYSLINUX 4.00 2010-06-28 EDD Load error - Boot error

After 64 prereleases, 626 commits, 52,742 lines of changes, and tons of work by many, many people, Syslinux 4.00 is now officially released. Syslinux 4.00 is the first of a set of major code restructuring releases. The single biggest new features are btrfs and ext4 support, and support for disks larger than 2 TiB. Huge thanks to: - Intel, for sponsoring mine, Alek Du's and Feng Tang's

Here's our testcase: #include <stdio.h> struct flags { unsigned frog: 1; unsigned foo : 1; unsigned bar : 1; unsigned bat : 1; unsigned baz : 1; unsigned bam : 1; }; int main() { struct flags flags; flags.bar = 1; flags.foo = 1; if (flags.foo == 1) { printf("Pass\n"); return 0; } else {

Hello. I'm having problems at instruction selection with my back end with the following basic-block due to a vector add with immediate constant vector (obtained by vectorizing a simple C program doing vector sum map): vector.ph: ; preds = %vector.memcheck50 %.splatinsert = insertelement <8 x i64> undef, i64 %i.07.unr, i32 0

Hi, Is there a kind of scope mechanism in the instruction lowering pattern language in order to control where instructions are inserted or how they are later reordered during the SelectionDiag linearization? I know the glue chain that stick instructions together. But such mechanism in not provided in instruction lowering pattern. I'm facing many situations where some patterns are lowered into

The DAG dumping will try to print some of the nodes "inline" (i.e. where they are used) to make the output more readable, so the dump of the DAG may not strictly reflect the node ordering. -Krzysztof On 5/4/2018 8:18 AM, Dominique Torette via llvm-dev wrote: > Here is a last example to illustrate my concern. > > The problem is about the lowering of node t13. > >

Here is a last example to illustrate my concern. The problem is about the lowering of node t13. Initial selection DAG: BB#0 '_start:entry' SelectionDAG has 44 nodes: t11: i16 = Constant<0> t0: ch = EntryToken t3: ch = llvm.clp.set.rspa t0, TargetConstant:i16<392>, Constant:i32<64> t5: ch = llvm.clp.set.rspb t3,

Krzysztof, Thanks for your interest to my questions. In order to clarify the context, here is the C source file of my test case. The 3 builtins initialize some stack pointers. They have to be executed before any other instruction. extern float fdivfaddfmul_a(float a, float b, float c, float d); volatile static float x1,x2,x3,x4; void _start(void) { float res;

Hi, the first attached patch extends the argument parsing code to allow (shell like) spaces. A config like LABEL BIOSupdate KERNEL dmiselect.c32 APPEND "ESPRIMO P5925" "memdisk initrd=/dos/FSC-E5925.img raw" will result in args[]: ESPRIMO P5925 memdisk initrd=/dos/FSC-E5925.img raw instead of (current code): "ESPRIMO P5925" "memdisk

Does the wiki actually send out emails to KaranbirSingh, RalphAngenendt, RussHerrold, TimVerhoeven, AkemiYagi, NedSlider, AlanBartlett, MarcusMoeller, TimothyLee, LaurentWandrebeck, TimoSchoeler, GaoHu, and AlainRegueraDelgado with every edit? It makes me a little nervous updating the T43 page or my homepage. I don't want to spam anyone. Cheers, Cody Jackson

Hi all; I just installed CentOS 5.6 on my IBM ThinkPad T43 and would like to add my experiences such far. The laptop I have is a different model than the previous editor's laptop (notably, it has an ATI Mobility Radeon X300, which required special drivers from elrepo, as opposed to the Intel graphics chip in the previous editor's laptop) and I think this bears mentioning in addition to

Hello all, i'm a newbie of R trying to make some statistical work in R environment. Now i have to laptops, one is Thinkpad X40 with Debian Lenny and the other is Thinkpad T43 with Ubuntu 8.10. Recently i met such problem and am wondering if anybody can do some help. After upgrading my /etc/apt/sources.list , i install R by apt-get install command. It works fine in both laptops. Then i

Hi, I recently downloaded and burned the 5.4 DVD ISO. All my machines are now running 5.4, but these are installs I performed with 5.0, 5.1, 5.2 etc. and then progressively upgraded. Now I had to use 5.4 because a friend's laptop, a brandnew Fujitsu Esprimo Mobile, refuses to boot anything under 5.4. After a fresh install of the base system, first thing I do is 'yum update' with

Hi Krzysztof, Sure, please see below. DAG.dump.() before and after, annotated with what I believe the DAG means. I've spent some time debugging the method but it's proving difficult to determine where the logic is misfiring. Disabling the entire combine causes a lot of failing x86-64 tests - I may have to learn an upstream vector ISA to make progress on this. Thank you >From your

Given that this is compiled with -O0, would there a way to skip the Optimization of the Type-legalized selection DAG? It's fine until it optimizes the Type-legalized selection DAG into the Optimized Type-legalized selection DAG.

Sanjay, I'm looking at some missed optimizations caused by D70246. Here's a test case: define <4 x float> @f(i32 %t32, <4 x float>* %t24) { .entry: %t43 = insertelement <3 x i32> undef, i32 %t32, i32 2 %t44 = bitcast <3 x i32> %t43 to <3 x float> %t45 = shufflevector <3 x float> %t44, <3 x float> undef, <4 x i32> <i32 0, i32 undef,

Hi, SystemZ supports @llvm.ctlz.i64() natively with a single instruction (FLOGR), and lesser bitwidth versions of the intrinsic are promoted to i64. For some reason, this leads to unfolded additions of constants as shown below: This function: define i16 @fun(i16 %arg) {   %1 = tail call i16 @llvm.ctlz.i16(i16 %arg, i1 false)   ret i16 %1 } ,gives this optimized DAG as input to instruction

Hi All, I have a question about splitting 'EXTRACT_VECTOR_ELT' with 'v2i1'. I have a llvm IR code snippet as following: llvm IR code snippet: for.body: ; preds = %entry, %for.cond %i.022 = phi i32 [ 0, %entry ], [ %inc, %for.cond ] %0 = icmp ne <2 x i32> %vecinit1, <i32 0, i32 -23> %1 = extractelement <2 x i1>
