* Fix PR1836: in the interpreter, read and write apintsDuncan Sands2007-12-101-24/+47
| | | | | | | | | | | | | | | | 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... llvm-svn: 44796

* My compiler complains that "x always evaluates to true"Duncan Sands2007-11-281-2/+6
| | | | | | | | | | | | | | | | | | | | | | | in this call: Result.IntVal = APInt(80, 2, x); What is x? uint16_t x[8]; I deduce that the APInt constructor being used is this one: APInt(uint32_t numBits, uint64_t val, bool isSigned = false); rather than this one: APInt(uint32_t numBits, uint32_t numWords, const uint64_t bigVal[]); That doesn't seem right! This fix compiles but is otherwise completely untested. llvm-svn: 44400

* Executive summary: getTypeSize -> getTypeStoreSize / getABITypeSize.Duncan Sands2007-11-014-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of getTypeSize was not clear - clarifying it is important now that we have x86 long double and arbitrary precision integers. The issue with long double is that it requires 80 bits, and this is not a multiple of its alignment. This gives a primitive type for which getTypeSize differed from getABITypeSize. For arbitrary precision integers it is even worse: there is the minimum number of bits needed to hold the type (eg: 36 for an i36), the maximum number of bits that will be overwriten when storing the type (40 bits for i36) and the ABI size (i.e. the storage size rounded up to a multiple of the alignment; 64 bits for i36). This patch removes getTypeSize (not really - it is still there but deprecated to allow for a gradual transition). Instead there is: (1) getTypeSizeInBits - a number of bits that suffices to hold all values of the type. For a primitive type, this is the minimum number of bits. For an i36 this is 36 bits. For x86 long double it is 80. This corresponds to gcc's TYPE_PRECISION. (2) getTypeStoreSizeInBits - the maximum number of bits that is written when storing the type (or read when reading it). For an i36 this is 40 bits, for an x86 long double it is 80 bits. This is the size alias analysis is interested in (getTypeStoreSize returns the number of bytes). There doesn't seem to be anything corresponding to this in gcc. (3) getABITypeSizeInBits - this is getTypeStoreSizeInBits rounded up to a multiple of the alignment. For an i36 this is 64, for an x86 long double this is 96 or 128 depending on the OS. This is the spacing between consecutive elements when you form an array out of this type (getABITypeSize returns the number of bytes). This is TYPE_SIZE in gcc. Since successive elements in a SequentialType (arrays, pointers and vectors) need to be aligned, the spacing between them will be given by getABITypeSize. This means that the size of an array is the length times the getABITypeSize. It also means that GEP computations need to use getABITypeSize when computing offsets. Furthermore, if an alloca allocates several elements at once then these too need to be aligned, so the size of the alloca has to be the number of elements multiplied by getABITypeSize. Logically speaking this doesn't have to be the case when allocating just one element, but it is simpler to also use getABITypeSize in this case. So alloca's and mallocs should use getABITypeSize. Finally, since gcc's only notion of size is that given by getABITypeSize, if you want to output assembler etc the same as gcc then getABITypeSize is the size you want. Since a store will overwrite no more than getTypeStoreSize bytes, and a read will read no more than that many bytes, this is the notion of size appropriate for alias analysis calculations. In this patch I have corrected all type size uses except some of those in ScalarReplAggregates, lib/Codegen, lib/Target (the hard cases). I will get around to auditing these too at some point, but I could do with some help. Finally, I made one change which I think wise but others might consider pointless and suboptimal: in an unpacked struct the amount of space allocated for a field is now given by the ABI size rather than getTypeStoreSize. I did this because every other place that reserves memory for a type (eg: alloca) now uses getABITypeSize, and I didn't want to make an exception for unpacked structs, i.e. I did it to make things more uniform. This only effects structs containing long doubles and arbitrary precision integers. If someone wants to pack these types more tightly they can always use a packed struct. llvm-svn: 43620

* VStudio compiler errors and placing Function*->ExFunc map under ↵Chuck Rose III2007-07-271-4/+5
| | | | | | | | | | | | | ManagedStatic control. This commit fixes two things. One is a pair of VStudio compiler errors stemming from variables which defined within the for loop statement and also within the body of the for loop. I fixed these by renaming one of the two variables. Additionally, I've made the Function*->ExFunc map in ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown. In repeated uses of the interpreter, where the same Function* address may get used for completely differnet functions, this was causing a crash. llvm-svn: 40558
