2021-04-20target/mips/rel6_translate: Change license to GNU LGPL v2.1 (or later)Philippe Mathieu-Daudé1-5/+4
When adding this file and its new content in commit 3f7a927847a ("target/mips: LSA/DLSA R6 decodetree helpers") I did 2 mistakes: 1: Listed authors who haven't been involved in its development, 2: Used an incorrect GNU GPLv2 license text (using 'and' instead of 'or'). Instead of correcting the GNU GPLv2 license text, replace the license by the 'GNU LGPL v2.1 or later' one, to be coherent with the other translation files in the target/mips/ folder.

2021-03-22target/mips/mxu_translate.c: Fix array overrun for D16MIN/D16MAXPeter Maydell1-4/+4
Coverity reported (CID 1450831) an array overrun in gen_mxu_D16MAX_D16MIN(): 1103 } else if (unlikely((XRb == 0) || (XRa == 0))) { .... 1112 if (opc == OPC_MXU_D16MAX) { 1113 tcg_gen_smax_i32(mxu_gpr[XRa - 1], t0, t1); 1114 } else { 1115 tcg_gen_smin_i32(mxu_gpr[XRa - 1], t0, t1); 1116 } >>> Overrunning array "mxu_gpr" of 15 8-byte elements at element index 4294967295 (byte offset 34359738367) using index "XRa - 1U" (which evaluates to 4294967295). This happens because the code is confused about which of XRa, XRb and XRc is the output, and which are the inputs. XRa is the output, but most of the conditions separating out different special cases are written as if XRc is the output, with the result that we can end up in the code path that assumes XRa is non-0 even when it is zero. Fix the erroneous code, bringing it in to line with the structure used in functions like gen_mxu_S32MAX_S32MIN() and gen_mxu_Q8MAX_Q8MIN().

2021-03-08clock: Add ClockEvent parameter to callbacksPeter Maydell1-1/+1
The Clock framework allows users to specify a callback which is called after the clock's period has been updated. Some users need to also have a callback which is called before the clock period is updated. As the first step in adding support for notifying Clock users on pre-update events, add an argument to the ClockCallback to specify what event is being notified, and add an argument to the various functions for registering a callback to specify which events are of interest to that callback.
