File gdb-testsuite-enable-some-test-cases-for-x86_64-m32.patch of Package gdb.27039
[gdb/testsuite] Enable some test-cases for x86_64 -m32 When trying to run test-case gdb.reverse/i387-env-reverse.exp for x86_64-linux with target board unix/-m32, it's skipped. Fix this by using is_x86_like_target instead of istarget "i?86-*linux*". This exposes a number of duplicates, fix those by making the test names unique. Likewise in a couple of other test-cases. Tested on x86_64-linux with target boards unix/-m32. --- gdb/testsuite/gdb.reverse/i386-precsave.exp | 2 +- gdb/testsuite/gdb.reverse/i386-reverse.exp | 2 +- gdb/testsuite/gdb.reverse/i387-env-reverse.exp | 121 +++++++------ gdb/testsuite/gdb.reverse/i387-stack-reverse.exp | 214 +++++++++++------------ 4 files changed, 166 insertions(+), 173 deletions(-) diff --git a/gdb/testsuite/gdb.reverse/i386-precsave.exp b/gdb/testsuite/gdb.reverse/i386-precsave.exp index e3fc940f5d0..54580474430 100644 --- a/gdb/testsuite/gdb.reverse/i386-precsave.exp +++ b/gdb/testsuite/gdb.reverse/i386-precsave.exp @@ -25,7 +25,7 @@ if ![supports_process_record] { } -if ![istarget "i?86-*linux*"] then { +if ![is_x86_like_target] then { verbose "Skipping i386 reverse tests." return } diff --git a/gdb/testsuite/gdb.reverse/i386-reverse.exp b/gdb/testsuite/gdb.reverse/i386-reverse.exp index 68e964e863c..15c18dad205 100644 --- a/gdb/testsuite/gdb.reverse/i386-reverse.exp +++ b/gdb/testsuite/gdb.reverse/i386-reverse.exp @@ -24,7 +24,7 @@ if ![supports_reverse] { } -if ![istarget "i?86-*linux*"] then { +if ![is_x86_like_target] then { verbose "Skipping i386 reverse tests." return } diff --git a/gdb/testsuite/gdb.reverse/i387-env-reverse.exp b/gdb/testsuite/gdb.reverse/i387-env-reverse.exp index 43c493dcca9..a0a79c22ed0 100644 --- a/gdb/testsuite/gdb.reverse/i387-env-reverse.exp +++ b/gdb/testsuite/gdb.reverse/i387-env-reverse.exp @@ -16,7 +16,7 @@ # This file is part of the gdb testsuite. -if ![istarget "i?86-*linux*"] then { +if ![is_x86_like_target] then { verbose "Skipping i387 reverse float tests." return } @@ -52,82 +52,79 @@ gdb_test "until $location" ".*$srcfile:$location.*" \ "rewind to beginning of main" gdb_test_no_output "set exec-dir forward" "set forward direction" -# Test FPU env particularly ftag and fstatus reigters. +with_test_prefix "forward" { + # Test FPU env particularly ftag and fstatus reigters. -set location [gdb_get_line_number "TEST ENV"] -gdb_test "until $location" ".*$srcfile:$location.*asm.*nop.*" \ -
