2017-11-10[testsuite/ARM] Consolidate sources for cmse testsThomas Preud'homme53-983/+545
For the most part, testcases under gcc.target/arm/cmse/baseline and gcc.target/arm/cmse/mainline are duplicate copies with only different dejagnu directives. Although there is no requirement for them to be similar, having them both identical allow to compare the code generated and make it easier in case of change in code generation to both architecture to update the testcases (if one needs updating so does the other). Similarly all the tests in gcc.target/arm/cmse/mainline/<floatabi> have the same source but are duplicate copies. This patch moves all the code in the tests to a parent directory: gcc.target/arm/cmse for tests shared by Armv8-M Baseline and Mainline and gcc.target/arm/cmse/mainline for tests *only* shared by the various float ABI of Armv8-M Mainline. C includes are then used where the code used to sit. Note that the cmse-13.c test used to differ slightly between architectures and float ABI tested in the first floating-point constant passed to bar: sometimes 1.0 and sometimes 3.0. This patch settles on 3.0 to not confuse with the 1.0 constant used to clear VFP registers in some of the configurations. 2017-11-10 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/testsuite/ * gcc.target/arm/cmse/bitfield-4.x: New file. * gcc.target/arm/cmse/baseline/bitfield-4.c: Remove code and include above file. * gcc.target/arm/cmse/mainline/bitfield-4.c: Likewise. * gcc.target/arm/cmse/bitfield-5.x: New file. * gcc.target/arm/cmse/baseline/bitfield-5.c: Remove code and include above file. * gcc.target/arm/cmse/mainline/bitfield-5.c: Likewise. * gcc.target/arm/cmse/bitfield-6.x: New file. * gcc.target/arm/cmse/baseline/bitfield-6.c: Remove code and include above file. * gcc.target/arm/cmse/mainline/bitfield-6.c: Likewise. * gcc.target/arm/cmse/bitfield-7.x: New file. * gcc.target/arm/cmse/baseline/bitfield-7.c: Remove code and include above file. * gcc.target/arm/cmse/mainline/bitfield-7.c: Likewise. * gcc.target/arm/cmse/bitfield-8.x: New file. * gcc.target/arm/cmse/baseline/bitfield-8.c: Remove code and include above file. * gcc.target/arm/cmse/mainline/bitfield-8.c: Likewise. * gcc.target/arm/cmse/bitfield-9.x: New file. * gcc.target/arm/cmse/baseline/bitfield-9.c: Remove code and include above file. * gcc.target/arm/cmse/mainline/bitfield-9.c: Likewise. * gcc.target/arm/cmse/bitfield-and-union.x: New file. * gcc.target/arm/cmse/baseline/bitfield-and-union-1.c: Rename into ... * gcc.target/arm/cmse/baseline/bitfield-and-union.c: This.

2017-11-10[testsuite] Fix retrieval of testnameThomas Preud'homme3-16/+68
When gcc-dg-runtest is used to run a test the test is run several times with different options. For clarity of the log, the test infrastructure then append the options to the testname. This means that all the code that must deal with the testcase itself (eg. removing the output files after the test has run) needs to remove the option name. There is already a pattern (see below) for this in several place of the testsuite framework but it is also missing in many places. This patch fixes all of these places. The pattern is as follows: set testcase [testname-for-summary] ; The name might include a list of options; extract the file name. set testcase [lindex $testcase 0] 2017-11-10 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/testsuite/ * lib/scanasm.exp (scan-assembler): Extract filename from testname used in summary.
