2022-03-23semihosting: clean up handling of expanded argvAlex Bennée
Another cleanup patch tripped over the fact we weren't being careful in our casting. Fix the casts, allow for a non-const and switch from g_realloc to g_renew. The whole semihosting argument handling could do with some tests though.

2022-02-28semihosting/arm-compat: replace heuristic for softmmu SYS_HEAPINFOAlex Bennée
The previous numbers were a guess at best and rather arbitrary without taking into account anything that might be loaded. Instead of using guesses based on the state of registers implement a new function that: a) scans the MemoryRegions for the largest RAM block b) iterates through all "ROM" blobs looking for the biggest gap The "ROM" blobs include all code loaded via -kernel and the various -device loader techniques.

2021-10-22target/riscv: Replace riscv_cpu_is_32bit with riscv_cpu_mxlRichard Henderson
Shortly, the set of supported XL will not be just 32 and 64, and representing that properly using the enumeration will be imperative. Two places, booting and gdb, intentionally use misa_mxl_max to emphasize the use of the reset value of misa.mxl, and not the current cpu state.

2021-09-13linux-user: Don't include gdbstub.h in qemu.hPeter Maydell
Currently the linux-user qemu.h pulls in gdbstub.h. There's no real reason why it should do this; include it directly from the C files which require it, and drop the include line in qemu.h. (Note that several of the C files previously relying on this indirect include were going out of their way to only include gdbstub.h conditionally on not CONFIG_USER_ONLY!)

2021-03-24semihosting/arm-compat-semi: don't use SET_ARG to report SYS_HEAPINFOAlex Bennée
As per the spec: the PARAMETER REGISTER contains the address of a pointer to a four-field data block. So we need to follow arg0 and place the results of SYS_HEAPINFO there.

2021-03-24semihosting/arm-compat-semi: unify GET/SET_ARG helpersAlex Bennée
>>>From the semihosting point of view what we want to know is the current mode of the processor. Unify this into a single helper and allow us to use the same GET/SET_ARG helpers for the rest of the code. Having the helper will also be useful later. Note: we aren't currently testing riscv32 due to missing toolchain for check-tcg tests.
