* std.fs.File.copyRange and copyRangeAll return u64 instead of usize -
the returned value is how much of the `len` is transferred, so the
types should match. This removes the need for an `@intCast`.
* fix typo that removed a subtraction
* Fix the size of codegen.AnyMCValue which gave me a compile error when
I tried to build self-hosted for i386-linux.
* restore the coercion to u64 of syms_sect.sh_info. We want to make
sure the multiplication happens with 64 bits and not the smaller type
used by the ELF format.
* fix another offset parameter in link/Elf.zig to be u64 instead of usize
* add a nice little TODO note to help out Jakub
* FmtError already has FileTooBig in it; we just need to return it.
It was regressed in 2 ways from the merge of #6250:
* it was not being enabled by default when the target OS is native.
* we were testing the libfoo.so file path existence with bogus format
string ('{}' instead of '{s}') and so it ended up being something
like "libstd.HashMap(K,V,...).Entry.so" instead of "libfoo.so". Using
{} rather than {s} is a footgun, be careful!
Previous functionality is now restored.
closes#6523
This commit refactors free space analysis (and VM analysis) somewhat.
This is still far from perfect, but at least it's not using any
hardcoded values.
This commit also reorganizes different flushing bits here and there,
so that bit common to Exe and Obj are put in the common path, while
Exe-specific are behind an appropriate switch/if statement.
* Convert draft to generate all relevant segments and sections in right places
* Do not prealloc space in text blocks until we can NOP
* Write out LC_LOAD_DYLINKER command
* Add LC_LOAD_DYLIB command in order to specify to load libSystem
* Redo update decl exports (similar to Elf globals, globals need to be contiguous in
memory)
This reverts commit c8b4cc2ff9cf15a42f95b2302e02431a0004f5c8.
This includes many C++ standard library headers:
#include <algorithm>
#include <chrono>
#include <ctime>
#include <iomanip>
#include <ios>
#include <iostream>
#include <memory>
#include <sstream>
#include <string>
#include <tuple>
#include <type_traits>
#include <vector>
which adds more than a second of compile time for each file that
includes the header:
ir.cpp before: 8.041s
ir.cpp after: 6.847s
Non-leaf functions now work. Combined with simple parameters and return
types, this allows more complicated programs than Hello World to be
correctly compiled.
