2021-01-12[gdb/testsuite] Require is_amd64_regs_target in gdb.base/disasm-optim.expTom de Vries2-1/+5
When running test-case gdb.base/disasm-optim.exp with target board unix/-m32, we get: ...

2021-01-12gdb: fix debug dump of OP_BOOL expressionsAndrew Burgess4-1/+24
Consider this GDB session: (gdb) set language fortran (gdb) set debug expression 1 (gdb) p .TRUE. Dump of expression @ 0x4055d90, before conversion to prefix form: Language fortran, 3 elements, 16 bytes each. Index Opcode Hex Value String Value 0 OP_BOOL 79 O............... 1 BINOP_ADD 1 ................ 2 OP_BOOL 79 O............... Dump of expression @ 0x4055d90, after conversion to prefix form: Expression: `TRUE' Language fortran, 3 elements, 16 bytes each. 0 OP_BOOL Unknown format 1 BINOP_ADD 2 OP_BOOL Unknown format 3 OP_NULL Unknown format $1 = .TRUE. The final dump of the OP_BOOL is completely wrong. After this patch we now get: (gdb) set language fortran (gdb) set debug expression 1 (gdb) p .TRUE. Dump of expression @ 0x2d07470, before conversion to prefix form: Language fortran, 3 elements, 16 bytes each.

2021-01-11sim: tests: get common tests working againMike Frysinger4-41/+46
These were written with 32-bit host assumptions baked into it. Simplify the printf formats to use ll length modifier as it's in C11 rather than trying to manually break it up into two, and cleanup some of the casts to stop assuming sizeof(long) is the same as sizeof(int). We also have to add a few more includes for the various funcs used in here. The tests aren't compiled automatically still. We can figure that out later with more work.

2021-01-11[gdb/testsuite] Fix gdb.arch/amd64-stap-three-arg-disp.STom de Vries2-3/+8
On SLE-11 I ran into: ... (gdb) print $_probe_arg0^M Cannot access memory at address 0x8000003fe05c^M (gdb) FAIL: gdb.arch/amd64-stap-special-operands.exp: probe: three_arg: \ print $_probe_arg0 ... The memory cannot be accessed because the address used to evaluate $_probe_arg0 at the probe point is incorrect. The address is calculated using this expression: ... .asciz "-4@-4(%rbp,%ebx,0)" ... which uses $ebx, but $ebx is uninitialized at the probe point. The test-case does contain a "movl $0, %ebx" insn to set $ebx to 0, but that insn is placed after the probe point. We could fix this by moving the insn to before the probe point. But, $ebx is also a callee-save register, so normally, if we modify it, we also need to save and restore it, which is currently not done. This is currently not harmful, because we don't run the test-case further than the probe point, but it's bound to cause confusion. So, fix this instead by using $eax instead in the expression, and moving the insn setting $eax to 0 to before the probe point. gdb/testsuite/ChangeLog: 2021-01-11 Tom de Vries <tdevries@suse.de> PR testsuite/26968 * gdb.arch/amd64-stap-three-arg-disp.S: Remove insn modifying $ebx.

2021-01-11sim: always call SIM_AC_OPTION_WARNINGSMike Frysinger2-1/+7
Now that all ports have opted in to this, we can require it in the core. It guarantees that new ports have them turned on, and defaults to -Werror in the hopes that new ports keep their code clean from the start. We do this as a sep commit to make it clear that there are no changes to existing ports as they've all explicitly called it already.
2021-01-11sim: call SIM_AC_OPTION_WARNINGS(no) in remaining portsMike Frysinger30-20/+1130
We want all ports to opt into extra warnings as the default compiler settings lets a lot slide. Opt all the ports that haven't already in to the warning system. None of them build with -Werror, so disable that by default. Hopefully someone finds these important enough to start fixing at some point.

2021-01-11sim: rl78: move storage out of headerMike Frysinger3-1/+8

2021-01-11sim: clean up C11 header includesMike Frysinger182-1090/+1097
Since we require C11 now, we can assume many headers exist, and clean up all of the conditional includes. It's not like any of this code actually accounted for the headers not existing, just whether we could include them. The strings.h cleanup is a little nuanced: it isn't in C11, but every use of it in the codebase will include strings.h only if string.h doesn't exist. Since we now assume the C11 string.h exists, we'll never include strings.h, so we can delete it.

PR 23672 points out a crash in compile_to_object. This crash came in during a C++-ization. This patch avoids the crash. The PR also points out another weird behavior in this code, but that one requires some setup that I don't have here, and it seems to date back to the introduction of the compile feature.

However, I've cleaned things up significantly from when this was first merged, and we can start to turn this around. Change the macro to enable -Werror by default, and allow ports to opt out. New ports will get it automatically (and we can push back on them if they try to turn it off). Also turn it off for the few ports that still hit warnings for me. All the rest will get the new default, and we'll wait for feedback if/when new issues come up.
