Previously the code for generating a panic crash expected
one of the parameters to be the error return trace. Now
it does not expect that parameter when g->have_err_ret_tracing
is false.
Closes#2276
Now that c58b80203443dcbf8b737ebdaa1f17fb20c77711 has removed
the "top of the comptime stack" requirement, the branch quota
can be modified somewhere other than the top of the comptime stack.
This means that the quota of a parent IrExecutable has to be
modifiable by an instruction in the child.
Closes#2261
ErrorInvalidFormat is not a fatal error so don't close the cache
manifest file right away but instead let cache_final() handle it.
Fixes the following (very common) warning when running the test suite:
Warning: Unable to write cache file [..]: unexpected seek failure
The seek failure is an lseek() system call that failed with EBADF
because the file descriptor had already been closed.
This removes the compiler_rt.setXmm0 hack. Instead, for
the functions that use i128 or u128 in their parameter and
return types, we use `@Vector(2, u64)` which generates
the LLVM IR `<2 x i64>` type that matches what Clang
generates for `typedef int ti_int __attribute__ ((mode (TI)))`
when targeting Windows x86_64.
there's a simple way to check for nan that does not need this header.
hryx on IRC reported that Linux Mint based on ubuntu 16.04, kernel
4.15.0, x86_64 did not have the isnan function.
Before only u0 was special cased in handling a dereference;
now all zero bit types are handled the same way. Dereferencing
a pointer to a zero bit type always gives a comptime-known
result.
This previously had been failing on master branch but went unnoticed
because until 846f72b57cb5 the CI server was mistakenly not actually
running the single-threaded tests with --single-threaded.
This fixes the standard library tests with --single-threaded
--release-fast.
This fixes comes thanks to Rich Felker from the musl libc project,
who gave me this crucial information:
"to satisfy the abi, your init code has to write the same value
to that memory location as the value passed to the [arch_prctl]
syscall"
This commit also changes the rules for when to build statically
by default. When building objects and static libraries, position
independent code is disabled if no libraries will be dynamically
linked and the target does not require position independent code.
