[LLVMdev] differences in IR and ELF?
...Constant *array = ConstantArray::get(type, a_elements); /* Make new GlobalVariable from array */ GlobalVariable *global = new GlobalVariable(M, type, true, my_linkage, array, "my array"); global->setSection(*my_section); } The IR looks like this: @"my array" = constant [3 x i32*] [i32* bitcast (i32 (i32)** @"Shadow Variable for ptr1" to i32*), i32* bitcast (i32 (i32)* @f2 to i32*), i32* bitcast (i32 (i32)* @f1 to i32*)], section "my_section" @"my array2" = constant [3 x i3...

[lld] RFC: Allow custom sections to be under GNU_RELRO
...th the fixed ".rel.ro" suffix for .data and .bss. Custom suffixes would also mean that the user code would depend more on implementation-specific things, i.e. prefixes. For example, one would wonder, should they annotate their data with __attribute__((section(...))) for ".data.rel.ro.my_section" or ".bss.rel.ro.my_section"? > The second is that you may be able to accomplish what you need with a linker script We discussed the possibility of using a custom linker script to achieve that. The main problem is that we're planning to ship the garbage collector as a library...

[LLVMdev] [RFC] Section Declarations in LLVM IR
...the section's linkage. - Sections don't have visibility, Values may disagree with one another about how visible they are. - Sections have attributes annotating what semantics they provide (read, write, execute, etc.) A concrete example of a const variable inside of a read-only section: $.my_section = appending read @my_var = constant float 1.0, section $.my_section, align 4 The following is how I imagine MS RTTI would look like if we had this IR construct: $.vdata_for_type = pick_largest read @my_rtti_for_type = pick_largest unnamed_addr constant %rtti_ptr_ty @rtti_complete_object_locator,...

Limiting getElementsByClassName to specific nodes and entities
I''m currently using "The Ultimate getElementsByClassName" (http://www.robertnyman.com/2005/11/07/the-ultimate-getelementsbyclassname/) instead of the Prototype version. This version seems to be faster since it lets you specify the starting node and the type of entity. For example: var widgets = getElementsByClassName(document, "ol", "tree"); Is

[lld] RFC: Allow custom sections to be under GNU_RELRO
Hey, We would like to propose an idea that would help security harden applications that define custom sections. Motivation and Background In Chromium we have a garbage collector that implements some RTTI machinery in the form of a table. This table is used by the collector to trace and finalize garbage collected objects. We're thinking of using __attribute__((section(...))) so that the table
