[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 2020-07-20 09:39:14 +02:00			`// RUN: llvm-mc -filetype=obj -triple i686-pc-linux-gnu %s -o - \| llvm-readobj --symbols - \| FileCheck %s`
ELFObjectWriter: deduplicate suffices in strtab We already do this for shstrtab, so might as well do it for strtab. This extracts the string table building code into a separate class. The idea is to use it for other object formats too. I mostly wanted to do this for the general principle, but it does save a little bit on object file size. I tried this on a clang bootstrap and saved 0.54% on the sum of object file sizes (1.14 MB out of 212 MB for a release build).

Don't create empty sections just to look like gas. We are long past the time when this much bug for bug compatibility was useful. llvm-svn: 251970 2015-11-03 21:02:22 +01:00			`// CHECK: Name: foobar (11)`
ELFObjectWriter: Don't sort non-local symbols As we don't sort local symbols, don't sort non-local symbols. This makes non-local symbols appear in their register order, which matches GNU as. The register order is nice in that you can write tests with interleaved CHECK prefixes, e.g. ``` // CHECK: something about foo .globl foo foo: // CHECK: something about bar .globl bar bar: ``` With the lexicographical order, the user needs to place lexicographical smallest symbol first or keep CHECK prefixes in one place. 2021-02-13 19:32:27 +01:00			`// CHECK: Name: foo (18)`
