2011-07-11arm-semi: Provide access to CLI arguments passed through the "-append" optionCédric VINCENT1-46/+67
This patch basically adapts the new semi-hosting command-line support -- introduced by Wolfgang Schildbach in the commit 2e8785ac -- for use in system-mode. Note that the "arm_cmdline_len" and "host_cmdline_len" variables were renamed respectively "input_size" and "output_size" because: * in C, the term "length" is generally used to count the number of character in a string, not to count the number of bytes in a buffer (as it is the case here). * in QEMU, the term "host" is used to name variables that are in the host address space, not to name variables in the target address space (as it is the case here). * in the case of this system-call, the terms "input" and "output" fit the semantic of the official ARM semi-hosting specification quite well. I know renaming can be considered harmful but I do think in this case the semantic really matters to keep this code more understandable.

2011-06-21arm-semi.c: Use correct check for failure of do_brk()Peter Maydell1-2/+3
In the ARM semihosting implementation of SYS_HEAPINFO, use the correct check for whether do_brk() has failed -- it does not return -1 but the previous value of the break limit. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2011-01-07Fix commandline handling for ARM semihosted executablesWolfgang Schildbach1-30/+49
Use the copy of the command line that loader_build_argptr() sets up in guest memory as the command line to return from the ARM SYS_GET_CMDLINE semihosting call. Previously we were using a pointer to memory which had already been freed before the guest program started. This fixes https://bugs.launchpad.net/qemu/+bug/673613 .
