We currently expect that the relocation type numbers are unique across
all architectures. But RISC-V and x86_64 use the same numbers for
different relocation types (R_X86_64_COPY = R_RISCV_JUMP_SLOT = 5).
So create a generic reloc type enum which maps to the arch-specific
reloc types instead of checking for all arch reloc types individually
everywhere.
Allowing creation of StorageDevicePartition objects for any arbitrary
BlockDevice objects means that we could technically create a
StorageDevicePartition for another StorageDevicePartition which is
obviously not the intention for this code. Instead, require to pass a
StorageDevice reference to ensure this cannot happen.
It is expected that these class members will be set when the object is
created (so they're set in the class constructor method) and never
change again, as its the driver responsibility to find these values
before creating a StorageDevice object.
This makes it easier to rely on these values later on as we don't expect
them to ever change for a StorageDevice object during its lifetime.
It calculated the disk size with the zero-based max addressable block
value.
For example, for a disk device with a block size of 512 bytes that has 2
LBAs so it can address LBA 0 and LBA 1 (so m_max_addressable_block is 1)
the calculated disk size will be 512 instead of 1024 bytes.
We remove can_read() and can_write(), as both of these methods should be
implemented for proper blocking support.
For our case, the previous code will simply block the user if they tries
to read beyond the max addressable offset, which is not a correct
behavior.
Instead, just do proper EOF guarding when calling read() and write() on
such objects.
Add a method for matehmatical operations when verifying IO operation
boundaries.
Also, make max_addressable_block method non-virtual, since no other
derived class actually has ever overrided this method.
This adds a basic `mkfs.fat` utility, which can format FAT12, FAT16
and FAT32 partitions.
This does have a few limitations, namely in that FAT12 formatting is
limited to a set known floppy disk sizes, and we can only generate
512-byte sectors.
Previously, we would remove the "longest extension" from each file name
when parsing it as the name of a utility, which made it impossible for
the names of utilities to contain any extensions.
This reflects what the functions does more accurately, and allows for
adding functions to get sizes through other methods.
This also corrects the return type of said function, as size_t may only
hold sizes up to 4GB on 32-bit platforms.
RFC9293 states that a closed socket should reply to all non-RST
packets with an RST. This change implements this behaviour as
specified in section 3.5.2 in bullet point 1.
Additionally, use the second bit (instead of the first) to differentiate
between strings and symbols there. This will allow transparent
conversion of DFS to StringBase in the future.
In a nutshell, when we understand that the expression is a function
call (this happens at '(' after an expression), stop parsing expression
and start parsing function arguments. This makes
`FunctionCallCanonicalizationPass` and the workaround for zero argument
function calls obsolete.
