Fix GCMetadaPrinter::finishAssembly not executed, patch by Yiannis Tsiouris. Due to the execution order of doFinalization functions, the GC information were deleted before AsmPrinter::doFinalization was executed. Thus, the GCMetadataPrinter::finishAssembly was never called. The patch fixes that by moving the code of the GCInfoDeleter::doFinalization to Printer::doFinalization. llvm-svn: 175528

; RUN: llc < %s -mtriple=x86_64-linux-gnu | FileCheck %s
; CHECK: .text
Always print the implicit .text at the start of an asm file. Before llvm-mc would print it, but llc was assuming that it would produce another section changing directive before one was needed. That assumption is false with inline asm. Fixes PR19049. Another option would be to always create the section, but in the asm printer avoid printing sections changes during initialization. That would work, but * We do use the fact that llvm-mc prints it in testing. The tests can be changed if needed. * A quick poll on IRC suggest that most developers prefer the implicit .text to be printed. llvm-svn: 203001

Remove AllowQuotesInName and friends from MCAsmInfo. Accepting quotes is a property of an assembler, not of an object file. For example, ELF can support any names for sections and symbols, but the gnu assembler only accepts quotes in some contexts and llvm-mc in a few more. LLVM should not produce different symbols based on a guess about which assembler will be reading the code it is printing. llvm-svn: 194575

[MC] Use .p2align instead of .align For historic reasons, the behavior of .align differs between targets. Fortunately, there are alternatives, .p2align and .balign, which make the interpretation of the parameter explicit, and which behave consistently across targets. This patch teaches MC to use .p2align instead of .align, so that people reading code for multiple architectures don't have to remember which way each platform does its .align directive.
