Hi, Can anyone fix this TEXTREL bug in ToT? https://bugs.gentoo.org/show_bug.cgi?id=403519 Thanks,

Hello > Can anyone fix this TEXTREL bug in ToT? > https://bugs.gentoo.org/show_bug.cgi?id=403519 The patch in PR is wrong since it will make both darwin and windows unhappy.

Hi, > The patch in PR is wrong since it will make both darwin and windows > unhappy. I will comment on gentoo PR about possible proper solution. I'll give it a try as you comment on the gentoo PR. But my ppc box is in my office, so I'll post a result on next Monday (JST). Thanks,

Hi, > You need to declare function like > > extern "C" { > static void* LLVM_ATTRIBUTE_USED > PPCCompilationCallbackC > <everything else goes here> > }; revised patch is filed and it works fine. https://bugs.gentoo.org/show_bug.cgi?id=403519#c16 https://bugs.gentoo.org/show_bug.cgi?id=403519#c17 so now this revised patch can be merged into ToT? Thanks,

...tion-specific sections). Currently, (in X86) we just write out a raw ".quad <label>" reference after lowering the function, where <label> is defined in the "xray_fn_idx" section. Unfortunately this causes the linker (gold?) to emit a relocation in the .text section (TEXTREL in ELF) which interferes unfavourably with GNU IFUNC relocations. Questions ========= Is there an alternative to this approach available to us from the LLVM back-end? I see that there's ways to define associative COMDAT sections, but that's COFF-specific and only works with COMDAT. We ins...

...That library (and in fact two other R libraries) all have non-PIC code in them, despite the fact the source is compiled with the -fPIC option. http://blogs.sun.com/rie/entry/my_relocations_don_t_fit shows how to prove this. If one runs this command on Solaris: $ elfdump -d libRblas.so | fgrep TEXTREL there is some output showing that theres non-PIC code present in the R library. R is compiled with -fPIC on Solaris, but certain things can cause non-PIC code to be generated even with that option. One is by the use of "computed gotos" which is a gcc extension. I'm wondering if R...
