Hi Kev, I'm glad to hear llvm-objdump is getting attention. I'm unclear on how much output specialization one could (or should) do for ELF vs. Mach-O. If you're game, let's compare an example: $ cat labeltest.s .text foo: nop bar: bum: nop jmp bar jmp bum jmp baz nop baz: nop Assembling for x86 and llvm-objdump'ing, i get $ llvm-mc -arch=x86 -filetype=obj labeltest.s -o x86_labeltest.o $ llvm-objdump -d x86_labeltest.o x86_labeltest.o: file format ELF32-i386 Disassembly of section .text: foo: 0: 90...

I have a bit of a riddle: In http://reviews.llvm.org/D19904 I'm trying to spell the following assembly: .palign 2, 0x90 jmp +0x9 nopw 512(%rax,%rax,1) // rest of the code I try the following snippet to accomplish this: OutStreamer->EmitLabel(CurSled); OutStreamer->EmitCodeAlignment(4); auto Target = OutContext.createLinkerPrivateTempSymbol(); // Use a two-byte `jmp`. This version of JMP takes an 8-b...

Hi, Currently X86 assembler seems to always compile "jmp _label" as a SHORT jump with "EB" opcode: $ echo "jmp _label"|llvm-mc -assemble -triple=i386 -show-encoding .text jmp _label # encoding: [0xeb,A] My question is: can X86 assembler supports NEAR jump with opcode "E9"? I try with &quot...

Hence my question. I dont know if there is any way to change this behavior. Looks like a bug to me so far. It isn't. It's just created some assembly which, when assembled, may end up as a near jump or a short jump. > Craig said t...

In creating a test case for a bug fix in llvm-objdump, I noticed that it differs in its output of pc-relative immediates from objdump: [secdev:/tmp] s$ cat a.s main: jmp .LBL0 .LBL0: ret [secdev:/tmp] s$ llvm-mc -filetype=obj a.s > a.o [secdev:/tmp] s$ objdump -d a.o |tail -n 2 0: eb 00 jmp 2 <main+0x2> 2: c3 retq [secdev:/tmp] s$ llvm-objdump -d a.o |tail -n 2 0: eb 00...

...it as a NEAR jump is because you need to alter the target of this jump to another address which may be out of a byte range.

Dear R friends, I know that this topic has been mulled over before, and that there is a substantial difference between the convergence criteria for JMP and those for R. I apologize that this is somwehat raking cold coals. Summary: A model/data combination achieves convergence in JMP, and survives a reasonably rigorous examination (sensible parameter estimates, well-behaved surface, confidence intervals exclude 0). The same combination fail...

Hi, I ran a small data set from a factorial experiment through R, Minitab and JMP... the result from R is significantly different from what Minitab or JMP give... The data set is at the following link: http://www.personal.psu.edu/nug107/Uploads/2x3_16repsANOVA.txt The first 5 columns are the factors and the next three are responses. In particular, for the response beta11MSE,...

Hi, Chris (cc) and I try to get the SGE master monitor work with Apple Leopard dtrace. Unfortunately we are stuck with the error msg below. Anyone having an idea what could be the cause? What I can rule out as cause is function inlining for the reasons explained below. Background information on SGE master monitor implementation is under http://wiki.gridengine.info/wiki/index.php/Dtrace
