search for: relocat

Hi, i''m searching to insert a relocatable image into a my plugin, but i don''t want to reimplement what was already done... i saw that in the gallery plugin there''s something like: <img src=\"{relocatable: #{imgname}}\"/> but i wasn''t able to reproduce this behavior.... How can i make this w...

A Toshiba CB35 Chromebook running Google's stock SeaBIOS reboots after selecting a relocatable kernel from extlinux 6.03. This is a regression caused by commit 8f470e7b movebits: Add syslinux_memmap_find() which factors syslinux_memmap_find() out of bios_boot_linux(). Prior to the refactoring, prot_mode_size was passed as the length in the first call to syslinux_memmap_type(). Af...

Initial issue is related to R_MIPS_GPREL16/32 relocations. When we calculate such relocations we need to know _gp symbol's value. This value might come from different sources. Usually we setup it using constant offset from the .got section. Also it might be defined by a linker script. And in rare but possible case it comes from .reginfo / .MIPS.op...

I've asked a question in the BioConductor list about package management. My solution depends on your answer to the following question. Are installed R packages "relocatable"? I mean relocatable in the same sense that files in a RedHat RPM file might be "relocatable" after compiling (http://www.rpm.org/max-rpm/ch-rpm-reloc.html). This allows one to build a package as the ordinary user and then the root user can take the result and put it wherever i...

.../ kernels > (versions)? Hi Ady, With a clone of the git repo on kernel.org I run make spotless bios; make bios ./bios/extlinux/extlinux -i {target mounted partition} The extlinux partition contains both kernels, ldlinux.sys, ldlinux.c32 and extlinux.conf, which is PROMPT 1 LABEL 1 LINUX {relocatable vmlinuz} APPEND root={target partition} LABEL 2 LINUX {nonrelocatable vmlinuz} APPEND root={target partition} I've heard that the SeaBIOS on these machines may report an incorrect amount of memory, requiring (at least older versions of) syslinux to use/pass "mem=1500m" or...

You are right. LLD does not have this problem. Initially I bumped into the MIPS specific bug related to GP relative relocations calculation. I tried to make reproduction script as general as possible and mistakenly make it too general. So now with your help I realized that the problem solely affects MIPS.

Hi, Now in case of relocatable object generation LLD merges and copies REL/RELA sections as is and does not touch any addends. But it is incorrect. If we have a relocation which targets a section, we have to adjust the relocation's addend to take in account that the section might be merged with other ones. Here is the r...

...ut it might be possible for the application I'm working on because a) a single thread manages all compilations sequentially, and b) the compiled methods don't make direct calls to other methods (so stubs will never be generated). What I need to know is, is the native code generated by LLVM relocatable such that it could be copied to another location in memory like this? Also, does LLVM do anything to the native code after it is first emitted? Does it try rewriting it, for example? Cheers, Gary -- http://gbenson.net/
