/*
|
||||
* Abstract bitfield class
|
||||
*
|
||||
* Allows endianness-independent access to individual bitfields within some raw
|
||||
* integer value. The assembly generated by this class is identical to the
|
||||
* usage of raw bitfields, so it's a perfectly fine replacement.
|
||||
*
|
||||
* For BitField<X,Y,Z>, X is the distance of the bitfield to the LSB of the
|
||||
* raw value, Y is the length in bits of the bitfield. Z is an integer type
|
||||
* which determines the sign of the bitfield. Z must have the same size as the
|
||||
* raw integer.
|
||||
*
|
||||
*
|
||||
* General usage:
|
||||
*
|
||||
* Create a new union with the raw integer value as a member.
|
||||
* Then for each bitfield you want to expose, add a BitField member
|
||||
* in the union. The template parameters are the bit offset and the number
|
||||
* of desired bits.
|
||||
*
|
||||
* Changes in the bitfield members will then get reflected in the raw integer
|
||||
* value and vice-versa.
|
||||
*
|
||||
*
|
||||
* Sample usage:
|
||||
*
|
||||
* union SomeRegister
|
||||
* {
|
||||
* u32 hex;
|
||||
*
|
||||
* BitField<0,7,u32> first_seven_bits; // unsigned
|
||||
* BitField<7,8,32> next_eight_bits; // unsigned
|
||||
* BitField<3,15,s32> some_signed_fields; // signed
|
||||
* };
|
||||
*
|
||||
* This is equivalent to the little-endian specific code:
|
||||
*
|
||||
* union SomeRegister
|
||||
* {
|
||||
* u32 hex;
|
||||
*
|
||||
* struct
|
||||
* {
|
||||
* u32 first_seven_bits : 7;
|
||||
* u32 next_eight_bits : 8;
|
||||
* };
|
||||
* struct
|
||||
* {
|
||||
* u32 : 3; // padding
|
||||
* s32 some_signed_fields : 15;
|
||||
* };
|
||||
* };
|
||||
*
|
||||
*
|
||||
* Caveats:
|
||||
*
|
||||
* 1)
|
||||
* BitField provides automatic casting from and to the storage type where
|
||||
* appropriate. However, when using non-typesafe functions like printf, an
|
||||
* explicit cast must be performed on the BitField object to make sure it gets
|
||||
* passed correctly, e.g.:
|
||||
* printf("Value: %d", (s32)some_register.some_signed_fields);
|
||||
*
|
||||
* 2)
|
||||
* Not really a caveat, but potentially irritating: This class is used in some
|
||||
* packed structures that do not guarantee proper alignment. Therefore we have
|
||||
* to use #pragma pack here not to pack the members of the class, but instead
|
||||
* to break GCC's assumption that the members of the class are aligned on
|
||||
* sizeof(StorageType).
|
||||
* TODO(neobrain): Confirm that this is a proper fix and not just masking
|
||||
* symptoms.
