2017-10-19RISC-V: Relax RISCV_PCREL_* to RISCV_GPREL_*Palmer Dabbelt4-8/+307
In the medany code model the compiler generates PCREL_HI20+PCREL_LO12 relocation pairs against local symbols because HI20+LO12 relocations can't reach high addresses. We relax HI20+LO12 pairs to GPREL relocations when possible, which is an important optimization for Dhrystone. Without this commit we are unable to relax PCREL_HI20+PCREL_LO12 pairs to GPREL when possible, causing a 10% permormance hit on Dhrystone on Rocket. Note that we'll now relax la gp, __global_pointer$ to mv gp, gp which probably isn't what you want in your entry code. Users who want gp-relative symbols to continue to resolve should add ".option norelax" accordingly. Due to this, the assembler now pairs PCREL relocations with RELAX relocations when they're expected to be relaxed just like every other relaxable relocation. bfd/ChangeLog 2017-10-19 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv.c (riscv_pcgp_hi_reloc): New structure.

2017-10-19RISC-V: Add R_RISCV_DELETE, which marks bytes for deletionPalmer Dabbelt4-4/+46
We currently delete bytes by shifting an entire BFD backwards to overwrite the bytes we no longer need. The result is that relaxing a BFD is quadratic time. This patch adds an additional relocation that specifies a byte range that will be deleted from the final object file, and adds a relaxation pass (between the existing passes that delete bytes and the alignment pass) that actually deletes the bytes. Note that deletion is still quadratic time, and nothing uses R_RISCV_DELETE yet. I've been meaning to go convert all the other relaxations to use R_RISCV_DELETE and then make it faster, but this patch has been sitting around for months so it looks like that won't happen for a bit. The PCREL->GPREL relaxation that comes next uses this, and since we've been using these two patches out of tree since I wrote them months ago I figure it's better to just get them in now. I (or someone else :)) can convert all the relocations later... R_RISCV_DELETE will never be emitted into ELF objects, so therefor isn't exposed to the rest of binutils. As such, we're not considering this as part of the ABI. bfd/ChangeLog 2017-10-19 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv (R_RISCV_DELETE): New define.

2017-10-19Fix inferior deadlock with "target remote | CMD"Pedro Alves5-0/+145
Comparing test results between --target_board=native-gdbserver --target_board=native-stdio-gdbserver I noticed that gdb.base/bigcore.exp is failing with native-stdio-gdbserver: Running src/gdb/testsuite/gdb.base/bigcore.exp ... FAIL: gdb.base/bigcore.exp: continue (timeout) ... The problem is that: 1. When debugging with "target remote | CMD", the inferior's stdout/stderr streams are connected to a pipe. 2. The bigcore.c program prints a lot to the screen before it reaches the breakpoint location that the "continue" shown above wants to reach. 3. GDB is not flushing the inferior's output pipe while the inferior is running. 4. The pipe becomes full. 5. The inferior thus deadlocks. The bug is #3 above, which is what this commit fixes. A new test is added, that specifically exercises this scenario. The test fails before the fix, and passes after, and gdb.base/bigcore.exp also starts passing. gdb/ChangeLog: 2017-10-19 Pedro Alves <palves@redhat.com> * ser-base.c (ser_base_read_error_fd): Delete the file handler if async.

2017-10-17Add several "quit with live inferior" testsPedro Alves3-0/+210
In my multi-target branch, I had managed to break GDB exiting successfuly in response to "quit" or SIGHUP/SIGTERM when: - you're debugging with "target extended-remote", - have more than one inferior loaded in gdb, some running, and at least one not running, and, - quit gdb with the inferior that is not running yet selected. The testsuite still passed cleanly anyway. I only noticed because I was left with a bunch of core dumps in the gdb/testsuite/ directory -- the testsuite infrastructure closes GDB's pty after running each testcase, which results in GDB getting a SIGHUP and should make GDB exit gracefully. If GDB crashes at that point though, there's no indication about it in gdb.sum/gdb.log. This commit adds a multitude of tests exercising quitting GDB with live inferiors, some of which would have caught the problem. gdb/testsuite/ChangeLog: 2017-10-17 Pedro Alves <palves@redhat.com> * gdb.base/quit-live.c: New file. * gdb.base/quit-live.exp: New file.

2017-10-17Correct -z text and other -z documentationAlan Modra2-95/+94
-z text applies to all dynamic binaries, not just shared libraries. A lot of the other options needed attention too. * ld.texinfo (-z): Combine negative options with corresponding positive option. Sort the table. Expand and correct "combreloc", "common", "common-page-size", "interpose", "loadfltr", "max-page-size", "muldefs", "nodefaultlib", "nodelete", "nodlopen", "nodump", "noextern-protected-data", "now", "origin", and "text".

2017-10-16Record and output access specifiers for nested typedefsKeith Seitz5-59/+264
We currently do not record access information for typedefs defined inside classes. Consider: struct foo { typedef int PUBLIC; private: typedef int PRIVATE; PRIVATE b; }; (gdb) ptype foo type = struct foo { private: PRIVATE b; typedef int PRIVATE; typedef int PUBLIC; } This patch fixes this: (gdb) ptype foo type = struct foo { private: PRIVATE b; typedef int PRIVATE; public: typedef int PUBLIC; } gdb/ChangeLog: * c-typeprint.c (enum access_specifier): Moved here from c_type_print_base. (output_access_specifier): New function. (c_type_print_base): Consider typedefs when assessing whether access labels are needed. Use output_access_specifier as needed. Output access specifier for typedefs, if needed. * dwarf2read.c (dwarf2_add_typedef): Record DW_AT_accessibility. * gdbtypes.h (struct typedef_field) <is_protected, is_private>: New fields. (TYPE_TYPEDEF_FIELD_PROTECTED, TYPE_TYPEDEF_FIELD_PRIVATE): New accessor macros. gdb/testsuite/ChangeLog: * gdb.cp/classes.cc (class_with_typedefs, class_with_public_typedef) (class_with_protected_typedef, class_with_private_typedef) (struct_with_public_typedef, struct_with_protected_typedef) (struct_with_private_typedef): New classes/structs. * gdb.cp/classes.exp (test_ptype_class_objects): Add tests for typedefs and access specifiers.
