2020-01-29cpu: move initCPU calls from initState to initAyaz Akram
This commit moves the initCPU calls from initState to init of base cpu (which were added in commit 0b8d02dec492215aa).

2020-01-25sim: Add a GuestABI mechanism to allocate space for a return value.Gabe Black
Some ABIs (including 32 bit ARM, 64 bit x86) allocate their argument registers differently depending on their return value. For instance, if the value needs to be returned in memory because it's too big, the caller could pass a pointer to where the result should be stored when the function returns. This pointer acts like an invisible first argument, offsetting where all the normal arguments actually live. This change adds a mechanism to handle that case. The Result templates can now declare an allocate() static method which is given a ThreadContext *, and a reference to the Position object. It can perform any adjustment it needs to before the normal argument extraction starts.

2020-01-23cpu: Fix ExeTraceRecord::traceInst.Gabe Black
A recent-ish change modified ExeTraceRecord::traceInst to make it more consistent with DPRINTF-s by using dprintf_flag to print the trace string. The generated string was passed as the format however, and that means that all % characters in the output (from register names, for example) are interpreted as format characters, mangling the output and making cprintf angry since there are no corresponding arguments. This change sets the format to "%s" instead, and passes the trace string as the first argument. The argument won't be parsed for format specifiers, and so should no longer get mangled.

2020-01-23sim: Eliminate the breakAtKernelFunction function.Gabe Black
It looks like this function is supposed to allow you to set up a PC based event which will trigger when the simulator executes a particular kernel function. That event doesn't actually do anything, but you can set a breakpoint there with gdb when debugging gem5 itself. There are a couple of problems with this function. First, it assumes that you want to set the breakpoint based on the first system in your simulation. Frequently simulations have only one system, but there isn't any rule that says they must, or any way to pick a different system. Second, this function assumes that you're in FS mode, that there is a kernel, and that there is a kernel symbol table to look symbols up in. On top of that, this function is a bit redundant since you can just use gdb to debug the kernel inside a simulated system.

Also, since the implementation was the same across all CPUs, this change collapses all the individual implementations down into the base CPU class.

2020-01-16arm: A couple small fixes for the arm64 bootloader makefile.Gabe Black
First, remove a deprecated flag that gcc no longer recognizes. Second, disable suffix based implicit makefile rules. These, in combination with the %.o: boot.S rule, were tricking make into deleting it's own makefile. How, you might ask? make wants to update its makefile, since that's a thing it does automatically. This is useful if you, for instance, have computed header dependencies. make decides it can make a file called "makefile" from a file called "makefile.o" by doing a linking step. make decides it can make makefile.o from boot.S from the %.o: boot.S rule, which it does. It then attempts to link makefile.o into makefile, but that fails because it lacks a "main" function since it's using a built in rule which doesn't know not to expect main. The makefile is clobbered in the process. make then deletes makefile.o because it was an implicit target, eliminating all the evidence.
