Casting to a union type is a gcc (and clang) extension. Other compilers might not support it. This is not a problem today, but the type casts can be removed easily. Smatch now no longer complains like before: linux-user/syscall.c:3190:18: warning: cast to non-scalar linux-user/syscall.c:7348:44: warning: cast to non-scalar Cc: Riku Voipio <riku.voipio@iki.fi> Signed-off-by: NStefan Weil <sw@weilnetz.de> Signed-off-by: NMichael Tokarev <mjt@tls.msk.ru>

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Same Coccinelle semantic patch as in commit b45c03f5.

ed173cb7 ".travis.yml: remove "make check" from main matrix" stopped running make check for all the Travis build targets for various reasons. It continued to run make check on one Travis build, which builds for a big list of all (? nearly all) our supported softmmu targets. Unfortunately, due to a spacing / quoting error it only actually builds for the alpha, arm, aarch64 and cris targets. Specifically, the list of targets is split over several lines. Even with YAML folding, this will leave spaces in the list, meaning $TARGETS won't have the value we need. I had a look at the YAML spec and I couldn't quickly see a way of splitting the list so that it doesn't end up with spaces, so this patch fixes the problem by putting the whole list on one huge line.

Generate an interrupt if the tx buffer is empty and the tx empty interrupt is enabled. This fixes a problem seen when running a Linux image since Linux commit 55c3cb1358e ("serial: imx: remove unneeded imx_transmit_buffer() from imx_start_tx()"). Linux now waits for the tx empty interrupt before starting to send data, causing transmit stalls until there is an interrupt for another reason.

At present, the "average" guestimate of TB size is way too small, leading to many unused entries in the pre-allocated TB array. For a guest with 1GB ram, we're currently allocating 256MB for the array. Survey arm, alpha, aarch64, ppc, sparc, i686, x86_64 guests running on x86_64 and ppc64 hosts and select a new average. The size of the array drops to 81MB with no more flushing than before. Reviewed-by: NAurelien Jarno <aurelien@aurel32.net> Signed-off-by: NRichard Henderson <rth@twiddle.net>

We currently pre-compute an worst case code size for any TB, which works out to be 122kB. Since the average TB size is near 1kB, this wastes quite a lot of storage. Instead, check for overflow in between generating code for each opcode. The overhead of the check isn't measurable and wastage is minimized.

By putting the prologue at the end, we risk overwriting the prologue should our estimate of maximum TB size.

This perhaps isn't ideal in terms of (ab)using the "pc" field to encode both pc and ppc + delay branch state, as one has to be aware of this when examining opcode dumps. But it preserves existing logic, which will be good for bisection, and it certainly does save storage space.
