[llvm-readobj] Update tests because of changes in llvm-readobj behavior This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar

// RUN: llvm-mc -filetype=obj -triple mipsel-unknown-linux %s -o -| llvm-readobj --symbols - | FileCheck %s
Remove some really nasty uses of hasRawTextSupport. When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. llvm-svn: 192035

Replace .mips_hack_stocg with ".set micromips" and ".set nomicromips". This matches what gnu as does and implementing this is easier than arguing about it. llvm-svn: 199181

.globl f1
Only mark functions as micromips. The GNU as behavior is a bit different and very strange. It will mark any label that contains an instruction. We can implement that, but using the type looks more natural since gas will not mark a function if a .word is used to output the instructions! llvm-svn: 199287
