## Test the behavior of the symbol reference section.

## Case1: a symbol can reference a section by SectionName or SectionIndex.
# RUN: yaml2obj --docnum=1 %s -o %t1
# RUN: llvm-readobj %t1 -s | FileCheck %s --check-prefix=CASE1

# CASE1:      Symbols [
# CASE1-NEXT:   Symbol {
# CASE1-NEXT:     Index: 0
# CASE1-NEXT:     Name: 
# CASE1-NEXT:     Value: 0x0
# CASE1-NEXT:     Section: .text
# CASE1-NEXT:     Type: 0x0
# CASE1-NEXT:     StorageClass: C_NULL (0x0)
# CASE1-NEXT:     NumberOfAuxEntries: 0
# CASE1-NEXT:   }
# CASE1-NEXT:   Symbol {
# CASE1-NEXT:     Index: 1
# CASE1-NEXT:     Name: 
# CASE1-NEXT:     Value: 0x0
# CASE1-NEXT:     Section: .text
# CASE1-NEXT:     Type: 0x0
# CASE1-NEXT:     StorageClass: C_NULL (0x0)
# CASE1-NEXT:     NumberOfAuxEntries: 0
# CASE1-NEXT:   }
# CASE1-NEXT: ]

FileHeader:

Sections:

Symbols:
  - Section: .text
  - SectionIndex: 1

## Case 2: a symbol can reference a section by both SectionName and SectionIndex.
# RUN: yaml2obj --docnum=2 -DSECNAME='.text' -DSECINDEX=1 %s -o %t2
# RUN: llvm-readobj %t2 -s | FileCheck %s --check-prefix=CASE2

# CASE2:      Symbols [
# CASE2-NEXT:   Symbol {
# CASE2-NEXT:     Index: 0
# CASE2-NEXT:     Name: 
# CASE2-NEXT:     Value: 0x0
# CASE2-NEXT:     Section: .text
# CASE2-NEXT:     Type: 0x0
# CASE2-NEXT:     StorageClass: C_NULL (0x0)
# CASE2-NEXT:     NumberOfAuxEntries: 0
# CASE2-NEXT:   }
# CASE2-NEXT: ]

FileHeader:
  MagicNumber: 0x1DF
Sections:
  - Name: .text
Symbols:
  - Section:      [[SECNAME=<none>]]
    SectionIndex: [[SECINDEX=<none>]]

## Case3: if both Section and SectionIndex are specified, but the two
##        values refer to different sections, an error will be reported.
# RUN: not yaml2obj --docnum=2 -DSECNAME='.text' -DSECINDEX=0 %s -o %t3 2>&1 \
# RUN:   | FileCheck %s --check-prefix=CASE3

# CASE3: the SectionName .text and the SectionIndex (0) refer to different sections

## Case4: yaml2obj allows the specification of an invalid SectionIndex.
## TODO: the error message should include the symbol name or index.
# RUN: yaml2obj --docnum=2 -DSECINDEX=2 %s -o %t4
# RUN: not llvm-readobj %t4 -s 2>&1 | FileCheck %s --check-prefix=CASE4

# CASE4: the section index (2) is invalid

## Case 5: if a symbol references a non-existent section by SectionName,
##         an error will be reported.
# RUN: not yaml2obj --docnum=2 -DSECNAME='.data' %s -o %t5 2>&1 \
# RUN:   | FileCheck %s --check-prefix=CASE5

# CASE5: the SectionName .data specified in the symbol does not exist
