| 2022-02-04 | sim: Allow toggling of quiet NaN-bit semantics | Faraz Shahbazker | 1 | -0/+4 | |
| IEEE754-1985 specifies the top bit of the mantissa as an indicator of signalling vs. quiet NaN, but does not define the precise semantics. Most architectures treat this bit as indicating quiet NaN, but legacy (pre-R6) MIPS goes the other way and treats it as signalling NaN. This used to be controlled by a macro that was only defined for MIPS. This patch replaces the macro with a variable to track the current semantics of the NaN bit and allows differentiation between older (pre-R6) and and newer MIPS cores. 2022-02-01 Faraz Shahbazker <fshahbazker@wavecomp.com> sim/common/ChangeLog: * sim-fpu.c (_sim_fpu): New. (pack_fpu, unpack_fpu): Allow reversal of quiet NaN semantics. * sim-fpu.h (sim_fpu_state): New struct. (_sim_fpu): New extern. (sim_fpu_quiet_nan_inverted): New define. sim/mips/ChangeLog: * cp1.h (fcsr_NAN2008_mask, fcsr_NAN2008_shift): New. * mips.igen (check_fpu): Select default quiet NaN mode for legacy MIPS. * sim-main.h (SIM_QUIET_NAN_NEGATED): Remove. | |||||

| 2019-01-01 | Update copyright year range in all GDB files. | Joel Brobecker | 1 | -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. | |||||
