2018-02-28build: use thin archives rather than incremental linkingNicholas Piggin1-1/+1
This changes to build system to use thin archives rather than incremental linking for built-in.o, similar to recent change to Linux. built-in.o is renamed to built-in.a, and is created as a thin archive with no index, for speed and size. All built-in.a are aggregated into a skiboot.tmp.a which is a thin archive built with an index, making it suitable or linking. This is input into the final link. The advantags of build size and linker code placement flexibility are not as great with skiboot as a bigger project like Linux, but it's a conceptually better way to build, and is more compatible with link time optimisation in toolchains which might be interesting for skiboot particularly for size reductions. Size of build tree before this patch is 34.4MB, afterwards 23.1MB. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2018-01-24PM: Fixed generation of MTSPR instruction in STOP API.Prem Shanker Jha1-1/+1
STOP API generates SPR restore instruction for a given SPR. Commit fixes the generation of mtspr instruction by API. Problem will show up only when API is changed to generate restore instruction using a GPR other than R0.

2017-11-20libpore: Fix incorrect mtspr instruction generationCyril Bur1-6/+4
>From coverity defect 173758: CID 173758 (#1 of 1): Unused value (UNUSED_VALUE) assigned_value: Assigning value from (uint8_t)i_Rs << 21 to mtsprInstOpcode here, but that stored value is overwritten before it can be used. This causes the generated mtspr to always move from register r0 as opposed to the function parameter i_Rs. Luckily the only call to getMtsprInstruction is: getMtsprInstruction( 0, (uint16_t)i_regId ); the first parameter is the register so in an incredible stroke of luck, the requirement is to generate a mtspr from r0. Therefore no bug exists today, this is still a fairly important fix because if anyone uses getMtsprInstruction() with a non zero first parameter, it will cause them endless headache.
