For attributes, we still parse the old syntax with the builtin non-string attributes after the ')' token, but that may be because it's just more readable. linker_private is still there because it's trivial to support. -------------- next part -------------- An HTML at...

Hi, I'm trying to understand better how linker_private (and friends) work. From what I can understand from the manual (http://llvm.org/docs/LangRef.html#linkage_linker_private), it seems that a linker_private function cannot be removed by the optimizers. Only the linker can discard the symbol. However, I tested with 'opt -O1' and a...

This patch introduces a the new "linker_private_weak" linkage type. Why a new linkage type? The idea behind the "linker" linkage types is that they are used by the linker and then discarded. I.e., the symbols won't show up in the final linked image. In that regard, all "linker" linkage types are inherently "...

As it currently stands, the symbol's prefix ("l") is the same for "linker_private" and "linker_private_weak". If this will always be the case, then I can remove the code in my patch that allows for a different prefix. > > I'm quite certain that it wi...

Hi all, I came across something that seems to be a bug in the dragonegg option that emits LLVM IR. ¿Can anybody reproduce the error, or see what's wrong? ¿Should I post it somewhere else in case it's really a bug? Thanks ahead! With this simple program: * #include <stdio.h> #include <string.h> int main(int argc, char** argv){ char a[8] = "aaaaaaa";

...ight and I think it was probably you! http://lab.llvm.org:8011/builders/dragonegg-x86_64-linux-gcc-4.6-test/builds/887 Here's a testcase. You can reproduce with "opt -instcombine". (The problem is that the code isn't expecting printf to return void). Ciao, Duncan. @.cst = linker_private unnamed_addr constant [8 x i8] c"A::A()\0A\00", align 8 define void @main() { call void (i8*, ...)* @printf(i8* getelementptr inbounds ([8 x i8]* @.cst, i64 0, i64 0)) ret void } declare void @printf(i8* nocapture, ...) nounwind

There were quiet a few format changes to the .ll in the process. Cheers, Rafael
