## Check that yaml2obj is able to customize the string table.
## `ContentSize`, `Length`, `Strings` and/or `RawContent` can be specified in
## YAML. Here we test the behaviour in various cases.
## Case 1: yaml2obj writes the default content (i.e. long symbol names in
## XCOFF32 or any symbol names in XCOFF64) when no StringTable field
## is specified.
# RUN: yaml2obj --docnum=1 %s -DSYMNAME='nameInStrTbl' -o %t1
# RUN: llvm-readobj %t1 --string-table | FileCheck %s --check-prefix=CASE1
# CASE1: StringTable {
# CASE1-NEXT: Length: 17
# CASE1-NEXT: [ 4] nameInStrTbl
# CASE1-NEXT: }

StringTable:
ContentSize: [[CONTENTSIZE=<none>]]
Length: [[LENGTHVALUE=<none>]]
RawContent: [[RAWCONTENT=<none>]]
## We can specify `ContentSize` only when the value is equal to or greater
## than the content size. For greater cases, zeros are added as padding.
## Cases 2-6 are trying to check this.
## Case 2: produce a string table with a specified `ContentSize`. In this case,
## there is no default content and the content is filled with zeroes.
# RUN: yaml2obj --docnum=1 %s -DCONTENTSIZE=20 -o %t2
# RUN: llvm-readobj %t2 -s --string-table | FileCheck %s --check-prefix=CASE2
# CASE2: StringTable {
# CASE2-NEXT: Length: 20
# CASE2-NEXT: }
## Case 3: if the value of `ContentSize` is greater than the content size,
## yaml2obj adds zeros as padding after the default content.
# RUN: yaml2obj --docnum=1 %s -DSYMNAME='nameInStrTbl' -DCONTENTSIZE=20 -o %t3
# RUN: llvm-readobj %t3 --string-table | FileCheck %s --check-prefix=CASE3
# CASE3: StringTable {
# CASE3-NEXT: Length: 20
# CASE3-NEXT: [ 4] nameInStrTbl
# CASE3-NEXT: }
## Case 4: the value of `ContentSize` matches the actual content size.
# RUN: yaml2obj --docnum=1 %s -DSYMNAME='nameInStrTbl' -DCONTENTSIZE=17 -o %t4
# RUN: llvm-readobj %t4 --string-table | FileCheck %s --check-prefix=CASE4
# CASE4: StringTable {
# CASE4-NEXT: Length: 17
# CASE4-NEXT: [ 4] nameInStrTbl
# CASE4-NEXT: }
## Case 5: an error is reported when the value of "ContentSize" is less than
## the content size.
# RUN: not yaml2obj --docnum=1 %s -DSYMNAME='nameInStrTbl' -DCONTENTSIZE=16 \
# RUN: -o %t5 2>&1 | FileCheck %s --check-prefix=CASE5
# CASE5: error: specified ContentSize (16) is less than the size of the data that would otherwise be written (17)
## Case 6: an error is reported when `ContentSize` is less than 4 without
## `RawContent`.
# RUN: not yaml2obj --docnum=1 %s -DCONTENTSIZE=3 -o %t6 2>&1 \
# RUN: | FileCheck %s --check-prefix=CASE6
# CASE6: error: ContentSize shouldn't be less than 4 without RawContent
## We can specify `Strings` for a string table. Default contents (ie. symbol
## names in string table) will be overwritten by specified values. Cases 7-9
## are trying to check this function.
## Case 7: produce a string table with specified `Strings` directly. In this
## case, there is no default content.
# RUN: yaml2obj --docnum=2 %s -o %t7
# RUN: llvm-readobj %t7 --string-table | FileCheck %s --check-prefix=CASE7
