* [codeview] Decode and dump FP regs from S_FRAMEPROC recordsReid Kleckner2018-09-111-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There are two registers encoded in the S_FRAMEPROC flags: one for locals and one for parameters. The encoding is described by the ExpandEncodedBasePointerReg function in cvinfo.h. Two bits are used to indicate one of four possible values: 0: no register - Used when there are no variables. 1: SP / standard - Variables are stored relative to the standard SP for the ISA. 2: FP - Variables are addressed relative to the ISA frame pointer, i.e. EBP on x86. If realignment is required, parameters use this. If a dynamic alloca is used, locals will be EBP relative. 3: Alternative - Variables are stored relative to some alternative third callee-saved register. This is required to address highly aligned locals when there are dynamic stack adjustments. In this case, both the incoming SP saved in the standard FP and the current SP are at some dynamic offset from the locals. LLVM uses ESI in this case, MSVC uses EBX. Most of the changes in this patch are to pass around the CPU so that we can decode these into real, named architectural registers.

* [ADT] Replace std::isprint by llvm::isPrint.Michael Kruse2018-07-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The standard library functions ::isprint/std::isprint have platform- and locale-dependent behavior which makes LLVM's output less predictable. In particular, regression tests my fail depending on the implementation of these functions. Implement llvm::isPrint in StringExtras.h with a standard behavior and replace all uses of ::isprint/std::isprint by a call it llvm::isPrint. The function is inlined and does not look up language settings so it should perform better than the standard library's version. Such a replacement has already been done for isdigit, isalpha, isxdigit in r314883. gtest does the same in gtest-printers.cc using the following justification: // Returns true if c is a printable ASCII character. We test the // value of c directly instead of calling isprint(), which is buggy on // Windows Mobile. inline bool IsPrintableAscii(wchar_t c) { return 0x20 <= c && c <= 0x7E; } Similar issues have also been encountered by Julia: https://github.com/JuliaLang/julia/issues/7416 I noticed the problem myself when on Windows isprint('\t') started to evaluate to true (see https://stackoverflow.com/questions/51435249) and thus caused several unit tests to fail. The result of isprint doesn't seem to be well-defined even for ASCII characters. Therefore I suggest to replace isprint by a platform-independent version.

* [llvm-readobj] - Teach tool to dump objects with >= SHN_LORESERVE of sections.George Rimar2018-07-181-4/+28
| | | | | | | | | | | | | | | | | | http://www.sco.com/developers/gabi/2003-12-17/ch4.eheader.html says that e_shnum and/or e_shstrndx may have special values if "the number of sections is greater than or equal to SHN_LORESERVE" or "the section name string table section index is greater than or equal to SHN_LORESERVE (0xff00)" Previously llvm-readobj was unable to dump such files, patch changes that. I had to add a precompiled test case because it does not seem possible to prepare a test using yaml2obj or llvm-mc (not clear how to make .shstrtab to have index >= SHN_LORESERVE).

This will help in uncovering non-determinism caused due to undefined sorting order of objects having the same key. To make use of that infrastructure we need to invoke llvm::sort instead of std::sort. Note: This patch is one of a series of patches to replace *all* std::sort to llvm::sort.
