2019-02-07Normalize include guards in gdbTom Tromey1-3/+3
While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

gdb/ChangeLog: Update copyright year range in all GDB files
2017-11-06Target FP: Handle interfaces to scripting languagesUlrich Weigand1-0/+5
The last remaing use for DOUBLEST is in the code that interfaces to the scripting languages (Python and Guile). The problem here is that we expose interfaces to convert a GDB value to and from native values of floating-point type in those languages, and those by definition use the host floating-point format. While we cannot completely eliminate conversions to/from the host floating-point format here, we still need to get rid of the uses of value_as_double / value_from_double, since those will go away. This patch implements two new target-float.c routine: - target_float_to_host_double - target_float_from_host_double which convert to/from a host "double". Those should only ever be used where a host "double" is mandated by an external interface. gdb/ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c (floatformat_to_host_double): New function. (floatformat_from_host_double): Likewise. (target_float_to_host_double): Likewise. (target_float_from_host_double): Likewise. * target-float.h (target_float_to_host_double): Add prototype. (target_float_from_host_double): Likewise. * guile/scm-value.c: Include "target-float.h". (gdbscm_value_to_real): Use target_float_to_host_double. Handle integer source values via value_as_long. * guile/scm-math.c: Include "target-float.h". Do not include "doublest.h", "dfp.h", and "expression.h". (vlscm_convert_typed_number): Use target_float_from_host_double. (vlscm_convert_number): Likewise. * python/py-value.c (valpy_float): Use target_float_to_host_double. (convert_value_from_python): Use target_float_from_host_double.
2017-11-06Target FP: Add binop and compare routines to target-float.{c,h}Ulrich Weigand1-0/+9
This patch adds the following target floating-point routines: - target_float_binop - target_float_compare which call the equivalent decimal_ routines to handle decimal FP, and call helper routines that currently still go via DOUBLEST to handle binary FP (derived from current valarith.c code). These routines are used to handle both binary and decimal FP types in scalar_binop, value_equal, and value_less, mostly following the method currently used for decimal FP. The existing value_args_as_decimal helper is renamed to value_args_as_target_float and extended to handle both binary and decimal types. The unary operations value_pos and value_neg are also simplified, the former by using a simple copy for all scalar types, the latter by using value_binop (... BINOP_SUB) to implement negation as subtraction from zero. ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c: Include <math.h>. (floatformat_binop): New function. (floatformat_compare): Likewise. (target_float_binop): Likewise. (target_float_compare): Likewise. * target-float.h: Include "expression.h". (target_float_binop): Add prototype. (target_float_compare): Likewise. * valarith.c: Do not include "doublest.h" and "dfp.h". Include "common/byte-vector.h". (value_args_as_decimal): Remove, replace by ... (value_args_as_target_float): ... this function. Handle both binary and decimal target floating-point formats. (scalar_binop): Handle both binary and decimal FP using value_args_as_target_float and target_float_binop. (value_equal): Handle both binary and decimal FP using value_args_as_target_float and target_float_compare. (value_less): Likewise. (value_pos): Handle all scalar types as simple copy. (value_neg): Handle all scalar types via BINOP_SUB from 0. * dfp.c (decimal_binop): Throw error instead of internal_error when called with an unsupported operation code.
2017-11-06Target FP: Add conversion routines to target-float.{c,h}Ulrich Weigand1-0/+12
This patch adds the following conversion routines: - target_float_to_longest - target_float_from_longest - target_float_from_ulongest - target_float_convert which call the equivalent decimal_ routines to handle decimal FP, and call helper routines that currently still go via DOUBLEST to handle binary FP. The target_float_convert routine not only handles BFP<->BFP and DFP<->DFP conversions, but also BFP<->DFP, which are implemented by converting to a string and back. These helpers are used in particular to implement conversion from and to FP in value_cast, without going through DOUBLEST there. In order to implement this for the FP<-integer case, the pack_long / pack_unsigned_long routines are extended to support floating-point values as output (thereby allowing use of value_from_[u]longest with a floating-point target type). This latter change also allows simplification of value_one. gdb/ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c (floatformat_to_longest): New function. (floatformat_from_longest, floatformat_from_ulongest): Likewise. (floatformat_convert): Likewise. (target_float_to_longest): Likewise. (target_float_from_longest, target_float_from_ulongest): Likewise. (target_float_convert): Likewise. * target-float.h (target_float_to_longest): Add prototype. (target_float_from_longest, target_float_from_ulongest): Likewise. (target_float_convert): Likewise. * value.c (unpack_long): Use target_float_to_longest. (pack_long): Allow FP types. Use target_float_from_longest. (pack_unsigned_long): Likewise using target_float_from_ulongest. * valops.c: Include "target-float.h". Do not include "dfp.h". (value_cast): Handle conversions to FP using target_float_convert, value_from_ulongest, and value_from_longest. (value_one): Use value_from_longest for FP types as well.
2017-11-06Target FP: Add string routines to target-float.{c,h}Ulrich Weigand1-0/+7
This adds target_float_to_string and target_float_from_string, which dispatch to the corresponding floatformat_ or decimal_ routines. Existing users of those routines are changed to use the new target-float routines instead (most of those places already handle both binary and decimal FP). In addition, two other places are changes to use target_float_from_string: - define_symbol in stabsread.c, when parsing a floating-point literal from stabs debug info - gdbarch-selftest.c when initializing a target format values (to eliminate use of DOUBLEST there). gdb/ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c (target_float_to_string): New function. (target_float_from_string): New function. * target-float.h (target_float_to_string): Add prototype. (target_float_from_string): Add prototype. * valprint.c: Include "target-float.h". Do not include "doublest.h" and "dfp.h". (print_floating): Use target_float_to_string. * printcmd.c: Include "target-float.h". Do not include "dfp.h".

2017-11-06Target FP: Introduce target-float.{c,h}Ulrich Weigand1-0/+28
This patch introduces the new set of target floating-point handling routines in target-float.{c,h}. In the end, the intention is that this file will contain support for all operations in target FP format, fully replacing both the current doublest.{c,h} and dfp.{c,h}. To begin with, this patch only adds a target_float_is_zero routine, which handles the equivalent of decimal_is_zero for both binary and decimal FP. For the binary case, to avoid conversion to DOUBLEST, this is implemented using the floatformat_classify routine. However, it turns out that floatformat_classify actually has a bug (it was not used to check for zero before), so this is fixed as well. The new routine is used in both value_logical_not and valpy_nonzero. There is one extra twist: the code previously used value_as_double to convert to DOUBLEST and then compare against zero. That routine performs an extra task: it detects invalid floating-point values and raises an error. In any place where value_as_double is removed in favor of some target-float.c routine, we need to replace that check. To keep this check centralized in one place, I've added a new routine is_floating_value, which returns a boolean determining whether a value's type is floating point (binary or decimal), and if so, also performs the validity check. Since we need to check whether a value is FP before calling any of the target-float routines anyway, this seems a good place to add the check without much code size overhead. In some places where we only want to check for floating-point types and not perform a validity check (e.g. for the *output* of an operation), we can use the new is_floating_type routine (in gdbarch) instead. The validity check itself is done by a new target_float_is_valid routine in target-float, encapsulating floatformat_is_valid. ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * Makefile.c (SFILES): Add target-float.c. (HFILES_NO_SRCDIR): Add target-float.h. (COMMON_OBS): Add target-float.o. * target-float.h: New file. * target-float.c: New file. * doublest.c (floatformat_classify): Fix detection of float_zero. * gdbtypes.c (is_floating_type): New function. * gdbtypes.h (is_floating_type): Add prototype. * value.c: Do not include "floatformat.h".
