* [scudo][standalone] Make tests work on FuchsiaKostya Kortchinsky2019-11-271-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This CL makes unit tests compatible with Fuchsia's zxtest. This required a few changes here and there, but also unearthed some incompatibilities that had to be addressed. A header is introduced to allow to account for the zxtest/gtest differences, some `#if SCUDO_FUCHSIA` are used to disable incompatible code (the 32-bit primary, or the exclusive TSD). It also brought to my attention that I was using `__scudo_default_options` in different tests, which ended up in a single binary, and I am not sure how that ever worked. So move this to the main cpp. Additionally fully disable the secondary freelist on Fuchsia as we do not track VMOs for secondary allocations, so no release possible. With some modifications to Scudo's BUILD.gn in Fuchsia: ``` [==========] 79 tests from 23 test cases ran (10280 ms total). [ PASSED ] 79 tests ``` Reviewers: mcgrathr, phosek, hctim, pcc, eugenis, cferris Subscribers: srhines, jfb, #sanitizers, llvm-commits Tags: #sanitizers, #llvm Differential Revision: https://reviews.llvm.org/D70682
* [scudo][standalone] Consolidate listsKostya Kortchinsky2019-10-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is a clean patch using the last diff of D69265, but using git instead of svn, since svn went ro and arc was making my life harded than it needed to be. I was going to introduce a couple more lists and realized that our lists are currently a bit all over the place. While we have a singly linked list type relatively well defined, we are using doubly linked lists defined on the fly for the stats and for the secondary blocks. This CL adds a doubly linked list object, reorganizing the singly list one to extract as much of the common code as possible. We use this new type in the stats and the secondary. We also reorganize the list tests to benefit from this consolidation. There are a few side effect changes such as using for iterator loops that are, in my opinion, cleaner in a couple of places.

* compiler-rt: Rename .cc file in lib/scudo/standalone/tests to .cppNico Weber2019-08-011-0/+260
Like r367463, but for scudo/standalone/tests. With this, all files in compiler-rt/lib have extension cpp. llvm-svn: 367569
