MC: AsmLexer: handle multi-character CommentStrings correctly As X86MCAsmInfoDarwin uses '##' as CommentString although a single '#' starts a comment a workaround for this special case is added. Fixes divisions in constant expressions for the AArch64 assembler and other targets which use '//' as CommentString. Patch by Janne Grunau! llvm-svn: 215615

// RUN: llvm-mc -triple aarch64-none-linux-gnu < %s | FileCheck %s
// Test that a single slash is not mistaken as the start of comment.
add support for -print-imm-hex for AArch64 Most immediates are printed in Aarch64InstPrinter using 'formatImm' macro, but not all of them. Implementation contains following rules: - floating point immediates are always printed as decimal - signed integer immediates are printed depends on flag settings (for negative values 'formatImm' macro prints the value as i.e -0x01 which may be convenient when imm is an address or offset) - logical immediates are always printed as hex - the 64-bit immediate for advSIMD, encoded in "a:b:c:d:e:f:g:h" is always printed as hex - the 64-bit immedaite in exception generation instructions like: brk, dcps1, dcps2, dcps3, hlt, hvc, smc, svc is always printed as hex - the rest of immediates is printed depends on availability of -print-imm-hex Signed-off-by: Maciej Gabka <maciej.gabka@arm.com> Signed-off-by: Paul Osmialowski <pawel.osmialowski@arm.com> Differential Revision: http://reviews.llvm.org/D16929 llvm-svn: 269446
