[PATCH v2 05/10] testsuite: Add check for unsupported TI ABI PRU features to testsuite

Not all C language features are supported when -mabi=ti option is used for PRU target. gcc/testsuite/ChangeLog: 2018-07-27 Dimitar Dimitrov * lib/gcc-dg.exp: Filter unsupported features in PRU's TI ABI mode. * lib/target-utils.exp: Ditto. * lib/target-supports.exp

[PATCH v2 04/10] testsuite: Add check for overflowed IMEM region to testsuite

PRU architecture supports maximum 256k program memory (IMEM). Some GCC test cases manage to produce executables bigger than that. gcc/testsuite/ChangeLog: 2018-07-27 Dimitar Dimitrov * lib/gcc-dg.exp: Bail on region overflow for tiny targets. * lib/target-utils.exp: Ditto

[PATCH 10/11] Fix LRA to handle multi-word eliminable registers

From: Dimitar Dimitrov For some targets, Pmode != UNITS_PER_WORD. Take this into account when marking hard registers as being used. I tested C and C++ testsuits for x86_64 with and without this patch. There was no regression, i.e. gcc.sum and g++.sum matched exactly. gcc/ChangeLog: 2018-06-13

HW subregs in machine description

Hello, I'm a newbie working on a GCC port [1] for PRU [2]. In order to achieve ABI compatibility with the proprietary TI toolchain, I need my Machine Description to support HW register subfields as indipendent first-class registers. I could not find a relevant example in the GCC source. Looks

Copyright assignment

Hello, I would like to contribute GCC and Binutils ports for PRU [1]. I think "assigment for all future changes" is suitable for me. Can I get the copyright assignment forms? Regards, Dimitar [1] https://github.com/dinuxbg/gnupru
