2021-12-17PPC64/TCG: Implement 'rfebb' instructionDaniel Henrique Barboza
An Event-Based Branch (EBB) allows applications to change the NIA when a event-based exception occurs. Event-based exceptions are enabled by setting the Branch Event Status and Control Register (BESCR). If the event-based exception is enabled when the exception occurs, an EBB happens. The following operations happens during an EBB: - Global Enable (GE) bit of BESCR is set to 0; - bits 0-61 of the Event-Based Branch Return Register (EBBRR) are set to the the effective address of the NIA that would have executed if the EBB didn't happen; - Instruction fetch and execution will continue in the effective address contained in the Event-Based Branch Handler Register (EBBHR). The EBB Handler will process the event and then execute the Return From Event-Based Branch (rfebb) instruction. rfebb sets BESCR_GE and then redirects execution to the address pointed in EBBRR. This process is described in the PowerISA v3.1, Book II, Chapter 6 [1]. This patch implements the rfebb instruction. Descriptions of all relevant BESCR bits are also added - this patch is only using BESCR_GE, but the next patches will use the remaining bits.

2021-12-17target/ppc: Fix xs{max, min}[cj]dp to use VSX registersVictor Colombo
PPC instruction xsmaxcdp, xsmincdp, xsmaxjdp, and xsminjdp are using vector registers when they should be using VSX ones. This happens because the instructions are using GEN_VSX_HELPER_R3, which adds 32 to the register numbers, effectively making them vector registers. This patch fixes it by changing these instructions to use GEN_VSX_HELPER_X3.

2021-12-17target/ppc: Fixed call to deferred exceptionLucas Mateus Castro (alqotel)
mtfsf, mtfsfi and mtfsb1 instructions call helper_float_check_status after updating the value of FPSCR, but helper_float_check_status checks fp_status and fp_status isn't updated based on FPSCR and since the value of fp_status is reset earlier in the instruction, it's always 0. Because of this helper_float_check_status would change the FI bit to 0 as this bit checks if the last operation was inexact and float_flag_inexact is always 0. These instructions also don't throw exceptions correctly since helper_float_check_status throw exceptions based on fp_status. This commit created a new helper, helper_fpscr_check_status that checks FPSCR value instead of fp_status and checks for a larger variety of exceptions than do_float_check_status. Since fp_status isn't used, gen_reset_fpstatus() was removed. The hardware used to compare QEMU's behavior to was a Power9.
