Fangrui Song 81cebfd008 [ELF][test] Change -o %t to -o /dev/null if the output is not needed 2020-02-12 21:54:50 -08:00
George Rimar ce6080819c [ELF] - Remove ScriptLexer::Error field and check ErrorCount instead.
D35945 introduces change when there is useless to check Error flag
in few places, but ErrorCount must be checked instead.

But then we probably can just check ErrorCount always. That should simplify
things. Patch do that.

Reid Kleckner 240cbabc6b Revert "Add a space to work around a Windows CPython / MSys quoting bug"
This reverts commit r284768.

After LLVM r285237, the lit shell interpreter works around this bug for
us.

Reid Kleckner 613c00db88 Add a space to work around a Windows CPython / MSys quoting bug
Summary:
The rules for quoting the command line that a subprocess receives are
user space conventions implemented by the C runtime. Python's quoting
rules are implemented here:
c30098c8c6/Lib/subprocess.py (L725)

The result is that the final command line C string computed by Python is
'echo \"'. Mingw doesn't appear to interpret that backslash as escaping
the quote because it is not already inside a quoted region. As a result,
our echo command prints a single backslash instead of a quote.

The whole issue can be sidestepped by adding a space a forcing Python to
put the argument to echo in double quotes.

George Rimar 50dcece2a0 Recommit r275257 "[ELF] - Implement extern "c++" version script tag"
BSD toolchain contains a bug:
https://sourceforge.net/p/elftoolchain/tickets/491/

In short demangler works differently, fix was to update the testcase.
It should fix the FreeBSD bot failture:
http://lab.llvm.org:8011/builders/lld-x86_64-freebsd/builds/19432/steps/test_lld/logs/stdio

Original commit message was:
[ELF] - Implement extern "c++" version script tag

Patch implements 'extern' version script tag.
Currently only values in quotes(") are supported.

Matching of externs is performed in the same pass as exact match of globals.

George Rimar 4d8465cbe1 [ELF] - Show explicit error if extern keyword is used in version script.
Since we do not have plans to support it in closest future,
it is better than common script parsing error.
