* [XCOFF][AIX] Generate symbol table entries with llvm-readobjJason Liu2019-08-271-20/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch implements main entry and auxiliary entries of symbol table generation for llvm-readobj on AIX. The source code of aix_xcoff_xlc_test8.o (compile with xlc) is: -bash-4.2$ cat test8.c extern int i; extern int TestforXcoff; extern int fun(int i); static int static_i; char* p="abcd"; int fun1(int j) { static_i++; j++; j=j+*p; return j; } int main() { i++; fun(i); return fun1(i); } Patch provided by DiggerLin Differential Revision: https://reviews.llvm.org/D65240 llvm-svn: 370097
* [llvm] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere2019-08-151-1/+1
| | | | | | | | Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. llvm-svn: 369013
* [XCOFF] Use a single symbolic constant for the size of an embeded name. [NFC]Sean Fertile2019-08-121-9/+9
| | | | | | | | | | Convert SymbolNameSize and SectionNameSize into just `NameSize`. The length of a name embeded in a symbol table entry or section header table entry is length 8 for Sections, Symbols and Files. No need to have a distinct constant for each one. Also removes the Size argument to 'generateStringRef' as the size is always 'XCOFF::NameSize'. llvm-svn: 368584
* [Object][XCOFF] Remove extra includes from XCOFF related files. [NFC]Sean Fertile2019-07-221-5/+0

* Try to appease the Windows build bots.Sean Fertile2019-07-091-4/+12
| | | | | | | Several of the conditonal operators commited in llvm-svn: 365524 fail to compile on the windows buildbots. Converting to an if and early return to try to fix. llvm-svn: 365535
* [Object][XCOFF] Add support for 64-bit file header and section header dumping.Sean Fertile2019-07-091-149/+253
| | | | | | | | | | | Adds a readobj dumper for 32-bit and 64-bit section header tables, and extend support for the file-header dumping to include 64-bit object files. Also refactors the binary file parsing to be done in a helper function in an attempt to cleanup error handeling. Differential Revision: https://reviews.llvm.org/D63843 llvm-svn: 365524
* [XCOFF] Implement parsing symbol table for xcoffobjfile and output as yaml ↵Jason Liu2019-05-281-39/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | format Summary: This patch implement parsing symbol table for xcoffobjfile and output as yaml format. Parsing auxiliary entries of a symbol will be in a separate patch. The XCOFF object file (aix_xcoff.o) used in the test comes from -bash-4.2$ cat test.c extern int i; extern int TestforXcoff; int main() { i++; TestforXcoff--; } Patch by DiggerLin Reviewers: sfertile, hubert.reinterpretcast, MaskRay, daltenty Differential Revision: https://reviews.llvm.org/D61532 llvm-svn: 361832
* [Object] Change ObjectFile::getSectionContents to return ↵Fangrui Song2019-05-141-3/+2
| | | | | | | | | | | | | | | | | | | Expected<ArrayRef<uint8_t>> Change std::error_code getSectionContents(DataRefImpl, StringRef &) const; to Expected<ArrayRef<uint8_t>> getSectionContents(DataRefImpl) const; Many object formats use ArrayRef<uint8_t> as the underlying type, which is generally better than StringRef to represent binary data, so change the type to decrease the number of type conversions.

* [Object][XCOFF] Add an XCOFF dumper for llvm-readobj.Sean Fertile2019-05-031-7/+34
| | | | | | | | | | | Patch adds support for dumping of file headers with llvm-readobj. XCOFF object files are added to test dumping a well formed file, and dumping both negative timestamps and negative symbol counts, both of which are allowed in the XCOFF definition.

* [Object] Change getSectionName() to return Expected<StringRef>Fangrui Song2019-05-021-5/+3
| | | | | | | | | | Summary: It currently receives an output parameter and returns std::error_code. Expected<StringRef> fits for this purpose perfectly. Differential Revision: https://reviews.llvm.org/D61421 llvm-svn: 359774
* [Object][XCOFF] Add intial support for section header table.Sean Fertile2019-04-251-29/+83
| | | | | | | | | Adds a representation of the section header table to XCOFFObjectFile, and implements enough to dump the section headers with llvm-obdump. Differential Revision: https://reviews.llvm.org/D60784 llvm-svn: 359244
* [XCOFF] Add functionality for parsing AIX XCOFF object file headersHubert Tong2019-04-041-0/+270
Summary: 1. Add functionality for parsing AIX XCOFF object files headers. 2. Only support 32-bit AIX XCOFF object files in this patch. 3. Print out the AIX XCOFF object file header in YAML format.
