2020-07-22Rollup merge of #74237 - lzutao:compiletest, r=Mark-SimulacrumManish Goregaokar-2/+2
compiletest: Rewrite extract_*_version functions This makes extract_lldb_version has the same version type like extract_gdb_version.
2020-07-22Rollup merge of #73893 - ajpaverd:cfguard-stabilize, r=nikomatsakisManish Goregaokar-4/+4
Stabilize control-flow-guard codegen option This is the stabilization PR discussed in #68793. It converts the `-Z control-flow-guard` debugging option into a codegen option (`-C control-flow-guard`), and changes the associated tests.
2020-07-22[AVR] Correctly set the pointer address space when constructing pointers to ↵Dylan McKay-0/+93
functions This patch extends the existing `type_i8p` method so that it requires an explicit address space to be specified. Before this patch, the `type_i8p` method implcitily assumed the default address space, which is not a safe transformation on all targets, namely AVR. The Rust compiler already has support for tracking the "instruction address space" on a per-target basis. This patch extends the code generation routines so that an address space must always be specified. In my estimation, around 15% of the callers of `type_i8p` produced invalid code on AVR due to the loss of address space prior to LLVM final code generation. This would lead to unavoidable assertion errors relating to invalid bitcasts. With this patch, the address space is always either 1) explicitly set to the instruction address space because the logic is dealing with functions which must be placed there, or 2) explicitly set to the default address space 0 because the logic can only operate on data space pointers and thus we keep the existing semantics of assuming the default, "data" address space.

2020-07-16Rollup merge of #74171 - ehuss:44056-debug-macos, r=nikomatsakisManish Goregaokar-2/+3
Fix 44056 test with debug on macos. The test `codegen/issue-44056-macos-tls-align.rs` fails on macos if `debug-assertions` is enabled in `config.toml`. It has the following error: ``` /Users/eric/Proj/rust/rust/src/test/codegen/issue-44056-macos-tls-align.rs:9:11: error: CHECK: expected string not found in input // CHECK: @STATIC_VAR_1 = thread_local local_unnamed_addr global <{ [32 x i8] }> zeroinitializer, section "__DATA,__thread_bss", align 4 ^ /Users/eric/Proj/rust/rust/build/x86_64-apple-darwin/test/codegen/issue-44056-macos-tls-align/issue-44056-macos-tls-align.ll:1:1: note: scanning from here ; ModuleID = 'issue_44056_macos_tls_align.3a1fbbbh-cgu.0' ^ /Users/eric/Proj/rust/rust/build/x86_64-apple-darwin/test/codegen/issue-44056-macos-tls-align/issue-44056-macos-tls-align.ll:9:1: note: possible intended match here @STATIC_VAR_1 = thread_local global <{ [32 x i8] }> zeroinitializer, section "__DATA,__thread_bss", align 4 ^ ``` Comparing the output, the actual output is missing the text "`local_unnamed_addr`". The fix here is to ignore `local_unnamed_addr`, as it doesn't seem relevant to the test.

Omit DW_AT_linkage_name when it is the same as DW_AT_name The DWARF standard suggests that it might be useful to include `DW_AT_linkage_name` when it is *distinct* from the identifier name. Fixes #46487. Fixes #59422.

2020-06-19Rollup merge of #73044 - tmiasko:compiletest-san, r=nikomatsakisRalf Jung-11/+6
compiletest: Add directives to detect sanitizer support Add needs-sanitizer-{address,leak,memory,thread} directive indicating that test requires target with support for specific sanitizer. This is an addition to the existing needs-sanitizer-support directive indicating that test requires a sanitizer runtime library. The existing needs-sanitizer-support directive could be incorporated into the new ones, but I decided to retain it, since it enables running sanitizer codegen tests even when building of sanitizer runtime libraries is disabled.

Fix codegen tests for RISC-V Some codegen tests didn't seem relevant (e.g. unsupported annotations). The RISC-V abi tests were broken by LLVM 10, c872dcf fixes that (cc: @msizanoen1) I'm not sure about skipping catch-unwind.rs and included that change here mostly as a request for comment - I can't tell if that's a bug.
