Implement address space attribute for LLVM pointer types. Address spaces are
...
regions of memory that have a target specific relationship, as described in the
Embedded C Technical Report.
This also implements the 2007-12-11-AddressSpaces test,
which demonstrates how address space attributes can be used in LLVM IR.
In addition, this patch changes the bitcode signature for stores (in a backwards
compatible manner), such that the pointer type, rather than the pointee type, is
encoded. This permits type information in the pointer (e.g. address space) to be
preserved for stores.
LangRef updates are forthcoming.

Fix PR1836: in the interpreter, read and write apints

using the minimum possible number of bytes. For little
endian targets run on little endian machines, apints are
stored in memory from LSB to MSB as before. For big endian
targets on big endian machines they are stored from MSB to
LSB which wasn't always the case before (if the target and
host endianness doesn't match values are stored according
to the host's endianness). Doing this requires knowing the
endianness of the host, which is determined when configuring -
thanks go to Anton for this. Only having access to little
endian machines I was unable to properly test the big endian
part, which is also the most complicated...

implement a readme entry, compiling the code into:
...
_foo:
movl $12, %eax
andl 4(%esp), %eax
movl _array(%eax), %eax
ret
instead of:
_foo:
movl 4(%esp), %eax
shrl $2, %eax
andl $3, %eax
movl _array(,%eax,4), %eax
ret
As it turns out, this triggers all the time, in a wide variety of
situations, for example, I see diffs like this in various programs:
- movl 8(%eax), %eax
- shll $2, %eax
- andl $1020, %eax
- movl (%esi,%eax), %eax
+ movzbl 8(%eax), %eax
+ movl (%esi,%eax,4), %eax
- shll $2, %edx
- andl $1020, %edx
- movl (%edi,%edx), %edx
+ andl $255, %edx
+ movl (%edi,%edx,4), %edx
Unfortunately, I also see stuff like this, which can be fixed in the
X86 backend:
- andl $85, %ebx
- addl _bit_count(,%ebx,4), %ebp
+ shll $2, %ebx
+ andl $340, %ebx
+ addl _bit_count(%ebx), %ebp

- Mark last use of a split interval as kill instead of letting spiller track it.
...
This allows an important optimization to be re-enabled.
- If all uses / defs of a split interval can be folded, give the interval a
low spill weight so it would not be picked in case spilling is needed (avoid
pushing other intervals in the same BB to be spilled).
