From e5d9fce03feeece7f53451da9fb958db2613d31e Mon Sep 17 00:00:00 2001 From: makise-homura Date: Tue, 5 Oct 2021 22:41:02 +0300 Subject: LCC: Add dedicated support for MCST LCC compiler Divert LCC compiler as a new one, instead of treating it as GNU. Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been passing checks for GNU compilers, so it has been identified as GNU. Now, with intent of seriously upstreaming its support, it has been added as a separate LCC compiler, and its version displays not a supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead of GNU 7.3.0). This commit adds its support for detection, and also converts basically every check like 'is this compiler GNU?' to 'is this compiler GNU or LCC?'. The only places where this check is untouched, is where it regards other platforms where LCC is unavailable (primarily non-Linux), and where it REALLY differs from GNU compiler. Note: this transition may break software that are already ported to Elbrus, but hardly relies that LCC will be detected as GNU; still such software is not known. --- Modules/CMakeParseImplicitLinkInfo.cmake | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'Modules/CMakeParseImplicitLinkInfo.cmake') diff --git a/Modules/CMakeParseImplicitLinkInfo.cmake b/Modules/CMakeParseImplicitLinkInfo.cmake index a61f71b117..6bdefde833 100644 --- a/Modules/CMakeParseImplicitLinkInfo.cmake +++ b/Modules/CMakeParseImplicitLinkInfo.cmake @@ -58,6 +58,10 @@ function(CMAKE_PARSE_IMPLICIT_LINK_INFO text lib_var dir_var fwk_var log_var obj endif() separate_arguments(args NATIVE_COMMAND "${line}") list(GET args 0 cmd) + if("${cmd}" MATCHES "->") + # LCC has '-> ' in-front of the linker + list(GET args 1 cmd) + endif() else() #check to see if the link line is comma-separated instead of space separated string(REGEX REPLACE "," " " line "${line}") -- cgit v1.2.1
