2020-06-05gas: avoid GCC 10 warning stringop-overflow in tc-bpf.cJose E. Marchesi2-2/+7
The GAS struct frag ends with a field `fr_literal' whose purpose is to mark the begining of the frag's data: struct frag { ... /* Data begins here. */ char fr_literal[1]; }; The code in gas/config/tc-bpf.c recently committed: where = fixP->fx_frag->fr_literal + fixP->fx_where; where[1] = target_big_endian ? 0x01 : 0x10; triggers the stringop-overflow warning in GCC 10+, since the compiler assumes the size of the modified buffer is 1 byte. This patch slightly modifies the code to make tc-bpf.c buildable with GCC 10+. 2020-06-05 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-bpf.c (md_apply_fix): Avoid GCC 10 warning stringop-overflow.

2020-06-04gdb: really share partial symtabs when using .gdb_index or .debug_namesSimon Marchi6-22/+152
Fix/follow-up to commit 17ee85fc2a ("Share DWARF partial symtabs"). In the non-index case, where GDB builds partial symbols from scratch, two objfiles around the same BFD correctly share partial symtabs. The first objfile, which has to do all the work, saves a reference to the created partial symtabs in the shared per_bfd object (at the end of dwarf2_build_psymtabs). The second objfile, when it reaches dwarf2_build_psymtabs, sees that there are already partial symtabs built for this BFD and just uses it. However, that commit missed implementing the same sharing for cases where GDB uses .gdb_index or .debug_names to build the partial symtabs. This patch fixes it by having the first objfile to use the BFD set per_bfd->partial_symtabs at the end of dwarf2_read_gdb_index / dwarf2_read_debug_names. For the subsequent objfiles using that BFD, the partial symtabs are then picked up in dwarf2_initialize_objfile. This patch adds a test that mimics how the issue was originally triggered: 1. Load the test file twice, such that the second objfile re-uses the per_bfd object created for the first objfile. 2. Run to some point where in the backtrace there is a frame for a function that's in a CU that's not yet read in. 3. Check that this frame's information is complete in the "backtrace" output. Step 2 requires an address -> symbol lookup which uses the addrmap at objfile->partial_symtabs->psymtabs_addrmap. If the objfile->partial_symtabs link is not properly setup (as is the case before this patch), the symbol for that frame won't be found and we'll get a frame with incomplete information. The test fails without the fix when using boards "cc-with-gdb-index" and "cc-with-debug-names". gdb/ChangeLog: * dwarf2/read.c (dwarf2_read_gdb_index): Save partial_symtabs in the per_bfd object. (dwarf2_read_debug_names): Likewise.

2020-06-04[gdb/testsuite] Fix error handling in gdb_file_cmdTom de Vries2-15/+13
Consider a gdb_load patch to call the gdb_file_cmd twice: ... proc gdb_load { arg } { if { $arg != "" } { + set res [gdb_file_cmd $arg] + if { $res != 0 } { + return $res + } return [gdb_file_cmd $arg] } return 0 } ... When running test-case gdb.base/index-cache.exp, we run into: ... ERROR: Couldn't load outputs/gdb.base/index-cache/index-cache, other program \ already loaded (timeout). FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: check index-cache \ stats (GDB internal error) ERROR: Couldn't load outputs/gdb.base/index-cache/index-cache, other program \ already loaded (timeout). ... The first timeout in more detail: ... (gdb) file outputs/gdb.base/index-cache/index-cache^M Load new symbol table from "index-cache"? (y or n) y^M Reading symbols from index-cache...^M src/gdb/dwarf2/read.c:2540: internal-error: \ void create_cus_from_index(dwarf2_per_bfd*, const gdb_byte*, offset_type, \ const gdb_byte*, offset_type): \ Assertion `per_bfd->all_comp_units.empty ()' failed.^M A problem internal to GDB has been detected,^M further debugging may prove unreliable.^M Quit this debugging session? (y or n) ERROR: Couldn't load index-cache, \ other program already loaded (timeout). ... Proc gdb_file_cmd has a gdb_expect handling the result of the file command, and if the result is a "Load new symbol table from index-cache? (y or n) " prompt, it sends a "y" and enters in a nested gdb_expect to handle the result. The first gdb_expect contains code to handle "A problem internal to GDB has been detected", but the second one doesn't, which causes the timeout. Fix this by removing the nested gdb_expect, and using exp_continue instead, such that we have instead: ... ERROR: Couldn't load outputs/gdb.base/index-cache/index-cache -- with new \ symbol table into gdb (GDB internal error). ERROR: Couldn't load outputs/gdb.base/index-cache/index-cache -- with new \ symbol table into gdb (GDB internal error). ...

2020-06-04opcodes: discriminate endianness and insn-endianness in CGEN portsJose E. Marchesi40-106/+178
The CGEN support code in opcodes accesses instruction contents using a couple of functions defined in cgen-opc.c: cgen_get_insn_value and cgen_put_insn_value. These functions use the "instruction endianness" in the CPU description to order the read/written bytes. The process of writing an instruction to the object file is: a) cgen_put_insn_value ;; Writes out the opcodes. b) ARCH_cgen_insert_operand insert_normal insert_1 cgen_put_insn_value ;; Writes out the bytes of the ;; operand. Likewise, the process of reading an instruction from the object file is: a) cgen_get_insn_value ;; Reads the opcodes. b) ARCH_cgen_extract_operand extract_normal extract_1 cgen_get_insn_value ;; Reads in the bytes of the ;; operand. As can be seen above, cgen_{get,put}_insn_value are used to both process the instruction opcodes (the constant fields conforming the base instruction) and also the values of the instruction operands, such as immediates. This is problematic for architectures in which the endianness of instructions is different to the endianness of data. An example is BPF, where instructions are always encoded big-endian but the data may be either big or little. This patch changes the cgen_{get,put}_insn_value functions in order to get an extra argument with the endianness to use, and adapts the existin callers to these functions in order to provide cd->endian or cd->insn_endian, whatever appropriate. Callers like extract_1 and insert_1 pass cd->endian (since they are reading/writing operand values) while callers reading/writing the base instruction pass cd->insn_endian instead. A few little adjustments have been needed in some existing CGEN based ports: * The BPF assembler uses cgen_put_insn_value. It has been adapted to pass the new endian argument. * The mep port has code in mep.opc that uses cgen_{get,put}_insn_value. It has been adapted to pass the new endianargument. Ditto for a call in the assembler. Tested with --enable-targets=all. Regested in all supported targets. No regressions. include/ChangeLog: 2020-06-04 Jose E.

This patch adds support for a new CGEN_OPEN_INSN_ENDIAN argument for @arch@_cgen_cpu_open. This is useful for architectures in which the endianness of the instruction words is not the same than the endianness used for data.

Don't do anything special with non-loaded, non-alloced sections. In particular, any relocs in such sections should not affect GOT and PLT reference counting (ie. we don't allow them to create GOT or PLT entries), there's no possibility or desire to optimize TLS relocs, and there's not much point in propagating relocs to shared libs that the dynamic linker won't relocate.
