David Tenty	98740643f7	[AIX] Emit TOC entries for ASM printing Summary: Emit the correct .toc psuedo op when we change to the TOC and emit TC entries. Make sure TOC psuedos get the right symbols via overriding getMCSymbolForTOCPseudoMO on AIX. Add a test for TOC assembly writing and update tests to include TOC entries. Also make sure external globals have a csect set and handle external function descriptor (originally authored by Jason Liu) so we can emit TOC entries for them.

Jason Liu	0dc0572b48	[XCOFF][AIX] Differentiate usage of label symbol and csect symbol Summary: We are using symbols to represent label and csect interchangeably before, and that could be a problem. There are cases we would need to add storage mapping class to the symbol if that symbol is actually the name of a csect, but it's hard for us to figure out whether that symbol is a label or csect. This patch intend to do the following: 1. Construct a QualName (A name include the storage mapping class) MCSymbolXCOFF for every MCSectionXCOFF. 2. Keep a pointer to that QualName inside of MCSectionXCOFF. 3. Use that QualName whenever we need a symbol refers to that MCSectionXCOFF. 4. Adapt the snowball effect from the above changes in XCOFFObjectWriter.cpp. Reviewers: xingxue, DiggerLin, sfertile, daltenty, hubert.reinterpretcast Reviewed By: DiggerLin, daltenty Subscribers: wuzish, nemanjai, mgorny, hiraditya, kbarton, jsji, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D69633	2019-11-08 09:30:10 -05:00

[AIX] Emit TOC entries for ASM printing

Summary:
Emit the correct .toc psuedo op when we change to the TOC and emit
TC entries. Make sure TOC psuedos get the right symbols via overriding
getMCSymbolForTOCPseudoMO on AIX. Add a test for TOC assembly writing
and update tests to include TOC entries.

Also make sure external globals have a csect set and handle external function descriptor (originally authored by Jason Liu) so we can emit TOC entries for them.

[XCOFF][AIX] Differentiate usage of label symbol and csect symbol

Summary:
 We are using symbols to represent label and csect interchangeably before, and that could be a problem.
There are cases we would need to add storage mapping class to the symbol if that symbol is actually the name of a csect, but it's hard for us to figure out whether that symbol is a label or csect.

This patch intend to do the following:
    1. Construct a QualName (A name include the storage mapping class)
       MCSymbolXCOFF for every MCSectionXCOFF.
    2. Keep a pointer to that QualName inside of MCSectionXCOFF.
    3. Use that QualName whenever we need a symbol refers to that
       MCSectionXCOFF.
    4. Adapt the snowball effect from the above changes in
       XCOFFObjectWriter.cpp.
