Andrew Kelley f488f3fd03 remove workaround for LLD bug 
Zig's embedded LLD now has a patch to resolve the deadlock race
condition, and the patch is getting upstreamed too, so this
closes #2283.

Andrew Kelley 579dd74114 fix Debug mode when error return tracing is off 
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

Andrew Kelley 68d7e4a1b6 better handle quota of setEvalBranchQuota 
Now that c58b802034 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

Shritesh Bhattarai 72bcd5a4a5 WIP: hello world 2019-04-13 15:15:39 -05:00
Ben Noordhuis 93e89b3b7e don't close cache manifest file prematurely 
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.
 2019-04-13 12:33:29 +02:00
Ben Noordhuis ea5518f69e make os_file_close poison file handle after close 
This helps track down use-after-close bugs.

Andrew Kelley 3ce024dd85 A bunch of fixes for the DWARF parser (#2254) 
* Correct parsing of DWARF line_info section

* Fix reading of udata/sdata encoded attributes

* Add definition for DW_AT_alignment

Even though it's been standardized in DWARF5 some compilers produce it
anyway for DWARF4 infos too.

* Fix reading of reference attributes

* Distinguish between absolute/relative addresses

Marc Tiehuis 78af62a19a Pack big.Int sign and length fields 
This effectively takes one-bit from the length field and uses it as the
sign bit. It reduces the size of an Int from 40 bits to 32 bits on a
64-bit arch.

This also reduces std.Rational from 80 bits to 64 bits.
