Those compilers support these features despite not being fully C++11-compliant.
<http://msdn.microsoft.com/en-us/library/hh567368.aspx> says that VS 2010
has "partial" support for override. I don't know what that entails and I
can't test it, so I err on the side of caution and only enable it in 2012
and up.
ScummVM would try to look up "confirm_exit" in the active domain,
even though the active domain had been removed and pointed to an
invalid address. To avoid this, try to keep _activeDomain and
_activeDomainName updated if removeGameDomain() removes the active
domain.
For good measure, also do it if the active domain is removed by
renameGameDomain(), though I don't know if there was any case where
this would have caused trouble.
MSVC8 gives various compile error relating to templates that were changed
back in 2008, leading me to belive that no one is using it, and that there
is not point adding work arounds for a 9 year old compiler no one uses.
Makes the DCT code use constants of type float in expressions which only use
type float values otherwise. This silences some floating point conversion
warnings in the DCT code.
Since we take a float parameter and return a float value we will also just
work on float values all the way. This silences some float conversion
warnings.
This removes the need for a hardware keyboard to trigger the use
of the virtual keyboard via F7 if using the default event mapper.
As middle button is rarely used by games, this should not cause any
conflicts. Though to avoid this possibility, the event is passed to
the engine.
These issues were identified by the STACK tool.
By default, the C++ new operator will throw an exception on allocation
failure, rather than returning a null pointer.
The result is that testing the returned pointer for null is redundant
and _may_ be removed by the compiler. This is thus optimization
unstable and may result in incorrect behaviour at runtime.
However, we do not use exceptions as they are not supported by all
compilers and may be disabled.
To make this stable without removing the null check, you could qualify
the new operator call with std::nothrow to indicate that this should
return a null, rather than throwing an exception.
However, using (std::nothrow) was not desirable due to the Symbian
toolchain lacking a <new> header.
A global solution to this was also not easy by redefining "new" as "new
(std::nothrow)" due to custom constructors in NDS toolchain and various
common classes.
Also, this would then need explicit checks for OOM adding to all new
usages as per C malloc which is untidy.
For now to remove this optimisation unstable code is best as it is
likely to not be present anyway, and OOM will cause a system library
exception instead, even without exceptions enabled in the application
code.
This reverts commit b585addc23de25c019f250986d50c0373219571d.
The allocation of MemoryPool's page memory is doing in MemoryPool::allocPage,
which uses ::malloc, thus we need to use ::free to free the page memory in
MemoryPool::freeUnusedPages.
Memory is allocated with new in Hashmap::allocNode() and incorrectly
freed with free() in ~MemoryPool() and freeUnusedPages().
