2016-11-22gas,opcodes: fix hardware capabilities bumping in the sparc assembler.Jose E. Marchesi9-73/+139
When the assembler finds an instruction which is part of a higher opcode architecture it bumps the current opcode architecture. For example: $ echo "mwait" | as -bump {standard input}: Assembler messages: {standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait" However, when two instructions pertaining to the same opcode architecture but associated to different SPARC hardware capabilities are found in the input stream, and no GAS architecture is specified in the command line, the assembler bangs: $ echo "mwait; wr %g0,%g1,%mcdper" | as -bump {standard input}: Assembler messages: {standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait" {standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr". ... and it should'nt, as WRMCDPER pertains to the same architecture level than MWAIT. This patch fixes this by extending the definition of sparc opcode architectures to contain a set of hardware capabilities and making the assembler to take these capabilities into account when updating the set of allowed hwcaps when an architecture bump is triggered by some instruction. This way, hwcaps associated to architecture levels are maintained in opcodes, while the assembler keeps the flexibiity of defining GAS architectures including additional hwcaps (like -Asparcfmaf or the v8plus* variants). A test covering this failure case is included. gas/ChangeLog: 2016-11-22 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c: Move HWS_* and HWS2_* definitions to opcodes/sparc-opc.c.

2016-11-21Create subobject value in pretty printerYao Qi6-36/+42
Nowadays, we create a value of subobject in pretty printer with 'address' being used, value = value_from_contents_and_address (type, valaddr + embedded_offset, address + embedded_offset); set_value_component_location (value, val); /* set_value_component_location resets the address, so we may need to set it again. */ if (VALUE_LVAL (value) != lval_internalvar && VALUE_LVAL (value) != lval_internalvar_component && VALUE_LVAL (value) != lval_computed) set_value_address (value, address + embedded_offset); value_from_contents_and_address creates a value from memory, but the value we are pretty-printing may not from memory at all. Instead of using value_from_contents_and_address, we create a value of subobject with the same location as object's but different offset. We avoid using address in this way. As a result, parameter 'address' in apply_val_pretty_printer is no longer needed, we can remove it in next step. We've already had the location of the 'whole' value, so it is safe to assume we can create a value of 'component' or 'suboject' value at the same location but with different offset. gdb: 2016-11-21 Yao Qi <yao.qi@linaro.org> * guile/scm-pretty-print.c (gdbscm_apply_val_pretty_printer): Don't call value_from_contents_and_address and set_value_address.

2016-11-18libiberty: demangler crash with missing :? or fold expression component.Mark Wielaard3-0/+19
When constructing an :? or fold expression that requires a third expression only the first and second were explicitly checked to not be NULL. Since the third expression is also required in these constructs it needs to be explicitly checked and rejected when missing. Otherwise the demangler will crash once it tries to d_print the NULL component. Added two examples to demangle-expected of strings that would crash before this fix. Found by American Fuzzy Lop (afl) fuzzer.

Add checks in various places to not advance the demangle string location and fail early when end of string is reached.

2016-11-17Makefile: Replace explicit subdir rules with pattern rulesSimon Marchi2-733/+236
When adding a .c file in subdirectory (e.g. mi/), the current practice is to add an explicit rule, such as: mi-cmd-break.o: $(srcdir)/mi/mi-cmd-break.c $(COMPILE) $(srcdir)/mi/mi-cmd-break.c $(POSTCOMPILE) I find it a bit verbose and cumbersome. Since we now require GNU make, we can change those rules with pattern rules, one for each subdirectory. For example, the following rule works for all files under mi: %.o: $(srcdir)/mi/%.c $(COMPILE) $< $(POSTCOMPILE) Those pattern rules assume that the source and target files have the same stem (foo.c and foo.o). In one case, common-agent.o is generated from common/agent.c, to avoid a conflict with the agent.o in gdb/. In this case, I kept the explicit rule, which takes precedence over the pattern rule. We could also rename common/agent.c to common/common-agent.c to get rid of the special case and still avoid the clash, as it is done with common/common-regcache.c, for example. This strategy was the least intrusive I found, as it only requires changing the rules, not the target names. I also considered two other solutions, which I did not like because I would have had to change target names a bit everywhere. - Replicate the source directory structure in the build directory, which would generate common/agent.o from common/agent.c. However, something was not right with the dependency tracking (the .deps directory). It's probably not hard to fix, but I did not investigate further. - Name the object files after the directory they are in, so that common/agent.c would generate common_agent.c. GDBserver can benefit from the same treatment, but I'll do it in another patch. Built-tested with --enable-targets=all.

2016-11-17Makefile: Replace old suffix rules with pattern rulesSimon Marchi4-8/+25
As mentioned here [1], suffix rules are obsolete and have been superseeded with pattern rules. People (myself included, before writing this patch) are more likely to know what pattern rules are than suffix rules. AFAIK, .SUFFIXES targets are only used for those rules, and can be removed as well. New in v2: - Replace rule in gdbserver/Makefile.in as well. [1] https://www.gnu.org/software/make/manual/html_node/Suffix-Rules.html gdb/ChangeLog: * Makefile.in (.c.o): Replace rule with ... (%.o: %.c): ... this one. (.po.gmo): Replace rule with ... (%.gmo: %.po): ... this one. (.po.pox): Replace rule with ... (%.pox: %.po): ... this one. (.y.c): Replace rule with ... (%.c: %.y): ... this one. (.l.c): Replace rule with ... (%.c: %.l): ... this one. (.SUFFIXES): Remove all instances. gdb/gdbserver/ChangeLog: * Makefile.in (.c.o): Replace rule with ... (%.o: %.c): ... this one.
